Description

Since upgrading to Gitea 1.16.1, clicking on a line of a file (in the source browsing view) no longer highlights it.
I notice in #17145 it is supposed to display a context menu, but I don't see it.

Strangely enough, when trying to reproduce on try.gitea.io, I see that it's working for some files, but not for others?

Working here:

• https://try.gitea.io/jpraet/tea/src/branch/master/main.go

Not working here:
