I need it for Widget, which moves to the modal version, with extended possibilities. An event beforeinput could solve my problem to some extent, but not in every case.

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Reproducible with current Nightly.

This appears to work the same in Chrome, so not a compat issue.

(In reply to James Graham [:jgraham] from comment #5)

This appears to work the same in Chrome, so not a compat issue.

So Chrome has changed the way it works, to the way Firefox works?
Because when I started this topic, Chrome worked differently.

This is still reproducible even with the fix of bug 1992288. I believe we should stop recreating TextEditor when the <input>/<textarea> is temporarily disconnected.
