Subject: [PATCH] Fix bogus http requests on diffs

The .blob-excerpt elements don't have these data attributes in some
cases resulting in bogus http request when expanding a diff and clicking
into the expanded area. This prevents those.

Should backport to 1.13.

Fixes: https://github.com/go-gitea/gitea/issues/13759
