**Steps to replicate the issue** (include links if applicable):
See [Recent changes](https://de.wikipedia.org/wiki/Spezial:Letzte_%C3%84nderungen?hidebots=1&hidecategorization=1&hideWikibase=1&tagfilter=mw-reverted&limit=500&days=30&urlversion=2) and e.g. [history 1](https://de.wikipedia.org/w/index.php?title=Migros&action=history) and [history 2](https://de.wikipedia.org/w/index.php?title=Migros&action=history). Other wikis such as meta are apparently not affected ([recent changes](https://meta.wikimedia.org/w/index.php?userExpLevel=unregistered%3Bnewcomer&hidebots=1&hidecategorization=1&hideWikibase=1&hidelog=1&hidenewuserlog=1&tagfilter=mw-reverted&limit=50&days=3&title=Special:RecentChanges&urlversion=2)).
**What happens?**:
Reverted main space edits are not tagged.
**What should have happened instead?**:
Reverted main space edits should be tagged as reverted.
**Other information** (browser name/version, screenshots, etc.):
Maybe this is related to FlaggedRevisions somehow as only dewiki and only the main namespace seems to be affected?
