Mobile text field problem with auto-closing keyboard and truncated text

[lorenzoMezza]

Hi everyone, I can't figure out how to make it so that when the user's input text exceeds the boundaries of its box, it gets truncated from the left instead of the right. In other words, when continuing to type, the new text should remain visible while the previous text is truncated.
Additionally, I'm not sure if it's a bug or a misconfiguration on my part, but in the NovaSamples.UIControls.TextFieldMobileInput class, there's a section of code that doesn't seem to work. Specifically, the part that handles closing the keyboard when the screen is touched outside of it.
It seems that this doesn't happen, and the keyboard remains open regardless. Here's the code in question that is not working:

private IEnumerator InputLoop()
{
    // Open the touch screen keyboard
    touchScreenKeyboardController.RequestShow(this, inputField.Text, new TouchScreenConfig()
    {
        KeyboardType = keyboardType,
        Autocorrection = autoCorrect,
        Multiline = allowNewlines,
        Secure = secure,
        Alert = false
    });

    // Update the touch screen keyboard selection
    UpdateTouchScreenKeyboardSelection();

    // Loop indefinitely, the loop will stop when the coroutine is stopped.
    while (true)
    {
        if (touchScreenKeyboardController.Status != TouchScreenKeyboard.Status.Visible)
        {
            // The touch screen keyboard was hidden (for example, if the user clicks somewhere else
            // on the screen), so unfocus the text input field (our unfocus event handler will 
            // stop this coroutine and do other cleanup).
            selector.RemoveFocus();
            yield break;
        }

        if (touchScreenKeyboardController.Text != inputField.Text)
        {
            // The keyboard text and input field text don't match, so update the input field
            updatingText = true;
            inputField.Text = touchScreenKeyboardController.Text;
            updatingText = false; 
        }

        // Convert the touch screen keyboard positions to display string positions
        TextPosition left = inputField.TextPositionFromStringIndex(touchScreenKeyboardController.Selection.start);
        TextPosition right = inputField.TextPositionFromStringIndex(touchScreenKeyboardController.Selection.end);

        if (left.IsValid && right.IsValid)
        {
            // Update the input field cursor positions
            inputField.SetCursorPosition(right, left);
        }

        yield return null;
    }
}

The problematic part is: if (touchScreenKeyboardController.Status != TouchScreenKeyboard.Status.Visible)
