I'm trying to ask questions (which uses the old editor), but pressing the "review your question" button does nothing. Checking "Answer your own question" does nothing (except make the checkmark appear in the box). Pressing "return" in the title/tags discards the draft.
Also, the new editor doesn't load. The toolbar has grey squares instead of buttons and won't let me type any text. Editing any post with it produces something similar, with no text in the box. This happens on Meta, Teams and Discussions.
Errors:
- [Error] SyntaxError: Invalid regular expression: invalid group specifier name (anonymous function) (ask.en.js:64)
- [Error] SyntaxError: Invalid regular expression: invalid group specifier name (anonymous function) (stacks-editor.en.js:64)
Browser: Chrome/Safari iOS; Safari MacOS (had to post from desktop Chrome)
The issue is the use of regex lookbehinds introduced in the code a week ago. The most used browser this affects is Safari 3.1 - 16.3 (both desktop and iOS). This includes the second to latest major version of Safari (16.x); the latest (17.x) wouldn't have this issue.
