On fr.wp at least a couple of edits were noticed that generated snowmen: https://fr.wikipedia.org/w/index.php?title=D%C3%A9sir_mim%C3%A9tique&diff=98365348&oldid=96841726 and https://fr.wikipedia.org/w/index.php?title=Andromaque&diff=98765089&oldid=97860409 (a vandalism). The snowman appears in the word "français(e)" (so it's possibly related to the ç character?). No other details available - the first editor didn't provide them, and the other was a vandal.
About the first case, where an external link was added and a <br> tag can also be observed, User:Drongou notes that it is "utterly incomprehensible. It's impossible to add a <br> vith VE, and VE itself does not seem to generate it. It must have come from copy/paste (snowmen are typical of failed copy/paste). Really strange, (one would rather expect a <br />): all the inclusions of <br> should be checked." I roughly translated his words. I didn't notice that before - he's right that adding <br> by hand in VE would produce nowiki tags, which are not there.
Here's another odd set of snowmen, this time at the Javanese Wikipedia. https://jv.wikipedia.org/w/index.php?title=Igor_Stravinsky&curid=73209&diff=881366&oldid=830233 The edit was inappropriate (poor English replacing Javanese) and was reverted.

I believe that we fixed the last of the snowmen issues (ha!) with the re-write last week; I've not been able to reproduce these edits at all now. Provisionally marking as FIXED.
