This is a known issue with HTML and Arabic characters, see for example the discussion here.

This issue only occurs on some browsers - on my macOS 12.6, Safari (v15.6) has this issue, while Chrome (v110) does not.

Given that this (possibly) stems from a WebKit bug, I am not sure if we can do much about this at the moment, but opening an issue in case someone has any ideas.
