Or read the whole thread starting
http://lists.w3.org/Archives/Public/public-script-coord/2013JanMar/0001.html if
desired.  Note that it's the third time or so this has come up, and each time
I've begged for a response from other UAs, with none from Apple thus far.

> This is WebKit's current behavior after garbage collection

Changing identity after garbage collection is by definition not web-detectable,
no (as long as expandos don't get lost in the process, and ignoring this
prototype issue)?  If the object was still pointed to by the web page, it
wouldn't get collected.

I'm talking about cases in which foo.firstChild.parentNode == foo suddenly
starts returning false, which is impossible right now but would no longer be
impossible with your proposal.
