Environment

• OS: Windows 10 Pro 22H2
• Avalonia-Version: 11.0.6+ (36e7ab5)

Additional context

The PR #13851 likely broke this. cc @RobertMut

There are issues with selection as well it seems.

I think we should consider reverting the related PRs before the next release. These issues make AutoCompleteBox unusable.

Original PR wasn't backported to 11.0, so we have a bit more time.

Hi, thanks for mentioning.
I've opened a pull request #14264 with a fix. By the accident I added CoerceCaretIndex to CaretIndexProperty in AutoCompleteBox, which caused this weird behaviour, if I understand correctly.
Sorry for causing trouble!

@RobertMut don't worry, we appreciate your contributions and also your sense of fixing things introduced by accident ❤️
