On https://www.wikidata.org/wiki/Q27084 I changed some 'de' aliases (https://www.wikidata.org/w/index.php?title=Q27084&diff=73060318&oldid=72595768).
Then wanted to change the link for enwiki from [[Parts-per notation]] to [[Parts per million]]. [[Parts per million]] is a redirect to [[Parts-per notation]] so the link switched back to [[Parts-per notation]]. This is ok. But in the revision history my previous edit was reverted: https://www.wikidata.org/w/index.php?title=Q27084&diff=73060363&oldid=73060318 this is a bug.
