Wikimedia Bugzilla is closed!

1) Open a translatable message: https://translatewiki.net/wiki/Special:Random/MediaWiki
2) Click edit
3) Above the qqq/docs section, click the "contribute" link to edit it
4) Do your edit and save

I. Expected: the popup is closed and I stay where I was or I'm redirected to some meaningful place.

II. Observed: https://translatewiki.net/w/api.php is opened in the same window, with content e.g.

{"edit":{"result":"Success","pageid":3174480,"title":"MediaWiki:Openid-convert-already-your-openid-text/qqq","contentmodel":"wikitext","oldrevid":4880899,"newrevid":4880906,"newtimestamp":"2013-08-05T11:08:24Z"}}

and the error console shows:
