Copy Link doesn't work in certain issue #455

In issues, you normally have this option "Copy Link" behind the three dots next to the comment, which - well - copies the link.

In issue #445 this doesn't work for me. Can someone reproduce?

Same here. Does not work in #445, but for example in this issue everything is fine.

browser console shows an error on issue #445 that might be related:

Please file a gitea bug if you can reproduce on https://try.gitea.io/.

works fine on try.gitea.io - tried with different issues and even a test migration with cloned issues of this repo.

Since other issues work, I thought to try to copy comment per comment and see if some content breaks something. But if you say that if you migrate the repo with issues and the same issue apparently works (?) then this is probably something else.
Generally I think it is most likely related to some content or settings of this specific issue.

Jep, here's the migrated test repo: https://try.gitea.io/bio1234/Community/issues/445

Just tried again and it now works on the referenced issue as well. Can you confirm @fnetX ?

Yeah, for me too. Nice.
