We are having this very same blocking issue. Here's what we were about to send to the Feedback Tracker, but thankfully I found this here. You can find reproductions attached.

In addition, this may be related or not, but the input interaction menu does now show up on the fields where the caret is broken. It's impossible to select all, paste, copy, etc.

Thanks for the bug report and test case, Pierre!

I tried out your test app, and observed that the bug still reproduces even after the above change. I’m currently working on a fix for your test case, which I’m tracking in <https://bugs.webkit.org/show_bug.cgi?id=201317>.
