Hey, I think they did make it, and Boris replied: http://lists.w3.org/Archives/Public/www-dom/2013JanMar/0068.html Unfortunately I do not know the details of the compatibility story. I'm just trying to work out what the specification should say.

I haven't tested this in a while, so I might be misremembering, but Gecko has magic to rewrite all JavaScript references to the old document to point to the new document. I don't know whether that magic is required by web compatibility, but I bet it is and I don't think we want to introduce more of that magic into WebKit. (We do something similar for Window today, but Window is a unique snowflake.) Adam ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-dev

We also keep the same Window (which it sounds like IE doesn't, since that's cited as an object that gets its prototype replaced). - Maciej > > Adam > > > On Thu, Jan 24, 2013 at 12:59 PM, Anne van Kesteren wrote: >> Hi, >> >> https://www.w3.org/Bugs/Public/show_bug.cgi?id=20567 could use input >> from the WebKit community, in particular DOM/JavaScript experts.

Re: [webkit-dev] DOM methods that affect [[Prototype]]
Note that WebKit re-uses the same Document after a call to document.open(). I suspect we're unlikely to change that behavior anytime soon.

Anne, can you help me get those comments sent to the w3 list? I sent them myself, but they seem to be held up or bounced?
