Indeed, I also notices some minor issues like that one after I upgraded
to 13.4.7-2~fto10+1. For me, e.g., the issue boards stay empty. In my
browser's web console I see two error messages among many warnings:
Loading module from
“https://git.example.org/group/project/-/boards/shortcuts/shortcuts” was
blocked because of a disallowed MIME type (“text/html”).
Loading module from
“https://git.example.org/group/project/-/boards/components/app.vue” was
blocked because of a disallowed MIME type (“text/html”).
My browser added an explanation link to these error messages pointing to
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Content-Type-Options.
Most notably, while the message about "app.vue" apparently appears on
all of my Gitlab pages, the messages about "shortcuts" is only present
at the issue board site.
