I've updated CodeMirror locally, hopefully that will mitigate this issue. It'll be live in the near future for you to test.

Update: With PCRE2 >7.3 flavour and multiline flag disabled, i can't delete typed text in regex box.

Just a slight improvement. I can delete text under these conditions now(a little cranky, i have to click delete button several times to make.it start the deletation). That's it. Everything else is still the same.
