This came from the VisualEditor feedback page in Hebrew. I couldn't replicate, but the problem is evident in this diff: http://he.wikipedia.org/w/index.php?title=%D7%A2%D7%96%D7%99_%D7%90%D7%99%D7%96%D7%91%D7%99%D7%A6%D7%A7%D7%99&diff=14341709&oldid=14341704 The user only changed the link at line 20 (blue, left) but VE seemed to have injected a bunch of wikitext into the template box above.
I couldnt reproduce it on https://he.wikipedia.org/wiki/User:John_Vandenberg/test I cant find any bug for visualeditor dumping in a subst:ed copy of a template. Very strange.
After talking to gwicke, this seems to be a temporary bug either related to some caching problem or an issue that was resolved, since it cannot be replicated and a lot of other updates were done that fixed related problems. Closed as likely fixed.
