Thread:VisualEditor/Feedback/VE freeze in Chrome when switching to code editor (2)

After editing https://fr.wikipedia.org/wiki/Adaptation_humaine_%C3%A0_la_haute_altitude for a while, I needed to switch to code, said that I would keep my changes and nothing happened except the page became grayed and froze. Clicked the green Save button but nothing. I can see my text but cannot select/copy it. Is it lost ???

in case it helps, here is what I see in the Chrome Console JQMIGRATE: Logging is active load.php?debug=false&lang=fr&modules=jquery%2Cmediawiki&only=scripts&skin=vector&version=20140814T1…:150 mediawiki.jqueryMsg: helppage: Unknown operation "ns" load.php?debug=false&lang=fr&modules=jquery%2Cmediawiki&only=scripts&skin=vector&version=20140814T1…:164 console.trace load.php?debug=false&lang=fr&modules=jquery%2Cmediawiki&only=scripts&skin=vector&version=20140814T1…:164 (repeated many times) mw.log.log.warn load.php?debug=false&lang=fr&modules=jquery%2Cmediawiki&only=scripts&skin=vector&version=20140814T1…:164 'Range.detach' is now a no-op, as per DOM (http://dom.spec.whatwg.org/#dom-range-detach).
