In my watchlist in the Hebrew Wikipedia I see edit summaries such as (<wbcreateclaim-create:1|: Property:P106: Q639669>). The corresponding entry in wikidata.org says Created claim: occupation (P106): musician (Q639669) (see https://www.wikidata.org/w/index.php?title=Q12410459&action=history&uselang=en ).
In Hebrew this looks especially ugly, because the RTL direction breaks the < and > characters and a bunch of other things in the appearance, but it's not supposed to happen in the first place, because a corresponding message seems to be translated, so it's just supposed to appear.
(Strangely, when I tried to reproduce this in English and Czech Wikipedias, I couldn't see Wikidata entries in my watchlist at all, but that's probably a different issue - T110825.)
