See https://en.wikipedia.org/w/index.php?title=Fizeau_experiment&diff=573001070&oldid=572299847 - the user corrected a typo and this resulted in the references groups getting duplicated. Reproduced in https://en.wikipedia.org/w/index.php?title=User:Elitre_(WMF)/Sandbox&diff=prev&oldid=573341379 and https://en.wikipedia.org/w/index.php?title=User:Elitre_(WMF)/Sandbox&diff=next&oldid=573340833 while just testing wikilinks, as you can see. My first attempt to reproduce this actually resulted in more weird (although known, I think) behaviour: https://en.wikipedia.org/w/index.php?title=User:Elitre_(WMF)/Sandbox&diff=prev&oldid=573176079 . Thanks.
