Crash: m_disconnectedNodesWithEventListeners not updated when nodes adopted

Thus it contains stale pointers.  The test cases crashes Safari every time for me (in debug mode), about to try release mode too.

I don't believe this is a security issue, but it is a p1 crasher.

test case (crashes Safari)

[Eric Seidel (no email)]

This crashes Debug mode for me, but might not crash release mode.  A way to make it crash release mode would be to probably force a GC between the two navigations.  I'm not sure I remember how to force a GC (probably allocate 1000 objects).

Yup.  Crashes every time in debug mode.  Not sure how to make release mode crash here.

This is the crashing stack trace, btw:

I can see the value in including the backtrace in a comment rather than as an attachment (it facilitates searches), but please do not paste all threads and the Binary Images section (I am sure you are not using unsupported extensions :-) ). Thanks!

I'm still in favor of this approach (the whole backtrace).  I find them easy to skip over (and most useful when pasted in their entirety).  But I'll try not to paste more than 1 in future bugs.

Fix disconneted event listener crasher

r=me

I'm not a fan of the pattern where EventTarget has methods that are really EventTargetNode-specific, but I guess it could be worse.
