The "moved paragraph" arrows we introduced with T139603: Show text changes when moving text chunks (#2) activate Page-Previews now and show broken popups:
This is because the link is an anchor link that points to the same page, with a fragment that points to the other side of the diff, e.g. #movedpara_5_0_rhs. These links do have a href and a title and are therefor considered possibly page links. They are not listed as BLACKLISTED_LINKS.
- Just adding diff-marker a to the blacklist might solve the issue already.
- We can as well add class="internal" to the arrow links in wikidiff2. This is already in the blacklist.
