- Line 132: Update the container-selection handling around
$isFullySelectedContainer so a nested ListNode is never returned or moved
without its owning ListItemNode; either reject nested-list-only selections or
promote the selection to the owning item and move both together. Preserve valid
outer-list movement and add a DOM test covering selection of every item in a
nested list.

<excerpt>node own several isolated editable regions ... s own `editorState` - ... root element can now be hosted in ... root (or iframe) This release also includes many other fixes and new ... across IME/composition, collaboration, markdown round-tripping, lists, code blocks, links, and mobile keyboards. It is also our first release (other than nightlies) to use NPM Trusted Publishing. Special recognition for this release goes to `@mayrang` for doing the majority of the work on both of these new features as well as fixing some tricky IME/composition issues 👏 `@levensta` has also been doing a fantastic job going through ... issue backlog, providing valuable feedback on ... bleeding edge features, and identifying long-standing edge cases. ... ## Breaking ... ### `lexical` — Node traversal methods no longer accept unsafe type parameters (`#8661`) The zero-argument generics on `getParent(OrThrow)`, `getPreviousSibling(s)`, `getNextSibling(s)`, `getChildren`, `getFirstChild(OrThrow)`, `getLastChild(OrThrow)`, `getChildAtIndex`, `getFirstDescendant`, `getLastDescendant`, and `getDescendantByIndex` were implicit unchecked casts — there is no inference site, so any non-base type argument was equivalent to an `as` cast. Each method is now an overload pair: a documented non-generic signature returning the base type (`LexicalNode` / `ElementNode | null`), plus the old generic signature marked `@deprecated`. Code that leaned on contextual-type inference no longer type-checks: ```ts // Before: compiled (unsound). After: type error. const node: ParagraphNode | null = $getRoot().getFirstChild(); // Port directly with an explicit cast (no behavior change): const node = $getRoot().getFirstChild() as ParagraphNode | null; // Or, better, narrow with a guard: const node = $getRoot().getFirstChild(); if ($isParagraphNode(node)) { /* node: ParagraphNode */ } ``` Existing `getFirstChild ()`-style calls still compile but are now deprecated and will be removed in a future release. This is a types-only change with no runtime impact. ### `lexical` — `$getNearestNodeFromDOMNode(rootElement)` now returns `RootNode` (`#8588`) The "selection captured outside of Lexical" mechanism is generalized beyond `DecoratorNode` subtrees: `setDOMUnmanaged(dom, {captureSelection: true})` now marks any subtree (e.g. a `DOMRenderExtension` override or a `getDOMSlot` widget) as selection-captured, and `isDOMCapturingSelection(dom)` walks ancestors so a descendant ` ` reports as captured. As part of this, the root element now carries a `__lexicalKey_*` stash, so `$getNodeFromDOM` / `$getNearestNodeFromDOMNode` resolve the root element to the `RootNode` instead of `null`. Two call sites become more correct (drop-on-root in clipboard, table-selection→range conversion), but **external callers that relied on `$getNearestNodeFromDOMNode(rootElement)` returning `null` must update**. The internal-only `$isSelectionCapturedInDecorator` was removed. ### `lexical` — `insertNodes` preserves a leading linebreak; managed ` `s are now tagged (`#8615`) `RangeSelection.insertNodes` now preserves the first `LineBreakNode` when inserting inline content ahead of a block element, instead of silently dropping it. Separately, the reconciler-inserted "managed" line breaks (the otherwise-invisible ` `s Lexical adds so the caret can land in empty lines) are now identifiable in the DOM as ` ` — and, on iOS Safari, an analogous ` ` in some cases. **DOM/HTML snapshot test expectations may need to ignore or expect this attribute.** Closes `#3980`. ### `@lexical/html` and node extensions — DOMImportExtension rules now register implicitly (`#8662`) _(experimental)_ The experimental DOM-import pipeline no longer requires you to list a per-package import extension. Each node-providing extension (`RichTextExtension`, `ListExtension`, `LinkExtension`, `TableExtension`, `CodeExtension`) now registers its own import rules, and the standalone `RichTextImportExtension` / `ListImportExtension` / `LinkIm…[truncated]</excerpt>

<title>Selection | Lexical</title>
<location>https://lexical.dev/docs/concepts/selection</location>
<excerpt>### `RangeSelection` ... This is the most common type of selection, and is a normalization of the browser&`#39`;s DOM Selection and Range APIs. `RangeSelection` consists of three main properties: ... - `anchor` representing a `RangeSelection` point - `focus` representing a `RangeSelection` point - `format` numeric bitwise flag, representing any active text formats ... Both the `anchor` and `focus` points refer to an object that represents a specific part of the editor. The main properties of a `RangeSelection` point are: ... - `key` representing the `NodeKey` of the selected Lexical node - `offset` representing the position from within its selected Lexical node. For the `text` type this is the character, and for the `element` type this is the child index from within the `ElementNode` - `type` representing either `element` or `text`. ... ### `NodeSelection` ... NodeSelection represents a selection of multiple arbitrary nodes. For example, three images selected at the same time. ... - `getNodes()` returns an array containing the selected LexicalNodes ... editor. update(() => { // Set ... range selection const rangeSelection = $createRangeSelection(); $setSelection(rangeSelection); // You can also indirectly create a range selection, by calling some of the selection // methods on Lexical nodes. const someNode = $getNodeByKey(someKey); // On element nodes, this will create a RangeSelection with type "element", // referencing an offset relating to the child within the element. // On text nodes, this will create a RangeSelection with type "text", // referencing the text character offset. someNode. select(); someNode. selectPrevious(); someNode. selectNext(); // You can use this on any node. someNode ... selectStart(); someNode. selectEnd(); ... // Set a node selection ... nodeSelection = $createNodeSelection(); // Add a node key to ... selection. nodeSelection. add(someKey); ... $setSelection(node ... You can also clear selection by setting it to `null`. $setSelection(null); });</excerpt>

Keep nested lists attached to their wrappers during cross-list moves.
For a selection from N through Z, Lexical 0.46 includes the nested ListNode and its wrapper. Since the nested list is fully selected, $getBlocksToMove maps it directly to the nested ListNode and bypasses $findBlockToMove. The handler then inserts that list before X, detaching it from its wrapper. A wrapper can also reach $findBlockToMove directly on partial nested-list selections.
Promote a selected wrapper to the atomic move block, keep the owner mapping for direct wrapper paths, and deduplicate after expanding nested wrappers.

Closed #81
Implement moving the blocks with
Alt+ArrowUp/Down.A block is the node containing the cursor together with all its nested nodes. Blocks can be moved only when there is a sibling in the corresponding direction.
Multiple selected blocks move together. For lists, a list item is moved together with its nested list, while a nested list cannot be moved independently.
