Chaining locators with lists does not work with Robot Framework 6.1 or above #1962
Description
Giving chained locator as a list of locators seems not to work since Robot Framework 6.1.0. Tested with Chrome and Firefox using test web page and test case given below. The first chained locator with >> finds the element, but latter with list does not . With Robot Framework 6.0.1 works fine. Tested also with RF 7.4.1 and not working.
I did some research in the SeleniumLibrary's code, and problem seems to be with the type annotations of the keywords. For example:
def click_element(
self,
locator: Union[WebElement, str],
modifier: Union[bool, str] = False,
action_chain: bool = False,
):
locator's type annotation should be `Union[WebElement, str, list]´. If I chance that, my test code passes.

Will take a look this morning. What version of pythonlibcore (robotframework-pythonlibcore) are you running? The latest is 4.5.0 released just this past week.

Thank you! robotframework-pythonlibcore version is 4.5.0. I added it to the description.

I think I am seeing the problem and yes it apopears to be the type annotation. I was temporarily confused because I know we had a test for this which was passing. Looking at the code who have just the one specific test, which should be good enough, but it was just the one keyword it uses,
Page Should Contain Element, that has the type annotations fixed. Looks like most if not all other keywords with locators do not ..Working on a solution now. Thanks for pointing this out @jjaakkola-atostek !
