Thanks for checking it on your side @Lilly! Definitely a strange issue then. It’s apparently working on my wife’s Mac, too, but not on either of mine (one of which I rarely use, runs an older OS, and is even physically located in a different country). As long as it’s not affecting other users I guess it’s not the end of the world, but still quite annoying.
But whatever is causing it, it may not be Discourse causing it then. Just strange that it works on Meta and not on my forum. I also don’t know what else could be causing it as I’ve disabled every extension or ad blocker etc that’s running on my machine.
Does anyone have any other ideas for what could be interfering with this very specific part of Discourse?
My Safari is at 16.3. I’ll try upgrading it to 16.6 and see if that solves it.
EDIT: I see that negative lookbehinds are only supported from 16.4, so the update should be likely to fix my previous issue—let’s see if this issue is related. However, I’m a bit concerned that my site will be broken for those on older Safari releases, especially when Safari updates are linked to OS updates.
