Issue
After T266067 added the mw-add-media and mw-remove-media tags, we see quite a few edits tagged even when there are no changes in media. Examples as follows.
- https://ja.wikipedia.org/w/index.php?diff=84377328 - adding link on a line with no media
- https://ja.wikipedia.org/w/index.php?diff=84383142 - punctuation change on a line with no media
- https://ja.wikipedia.org/w/index.php?diff=84410833 - a page move
This affects T265771 as it means the statistics from these tags are inaccurate.
What should have happened instead:
The edits mentioned above should not be tagged.
