Invalid regular expression crash on iOS < 16.4 due to named capturing groups

[pietrangeloalberto]

Describe the bug
BlockNote (or one of its dependencies) is using modern regular expressions with named capturing groups (e.g. /(?...)/) which are not supported in Safari < 16.4.

This causes a syntax error and blocks rendering or functionality when using the editor on iOS < 16.4.

Example error:

SyntaxError: Invalid regular expression: invalid group specifier name

To Reproduce
Environment
iOS version:
iOS 15.x / iOS 16.2 / iOS 16.3 (Safari)

BlockNote version:
"@blocknote/core": "^0.31.1",
"@blocknote/react": "^0.31.1"

Bundler: Next.js with SWC

Misc

• Browser: Safari iOS < 16.4

I did not find any named capture groups in our codebase, so it must be one of our dependencies which we obviously would have little influence on.

I suggest you bring it up with the project that is using them rather than posting here. Also, to further help with this, I would at least need a stack trace
