Is this documented anywhere? By "compatibility problems", presumably you
mean bugs in Firefox that were then exploited by content authors who didn't
know better? From Maciej's description of WebKit's behaviour, it looks
like either they didn't know about this consensus or they didn't implement
This definitely needs to be documented in HTML5.

in DOM Core in the pipeline that I need to know about? I already know about

That leaves the issue of how adoptNode() affects the [[Prototype]] of the
node objects, which is currently inconsistent between desktop browsers.
Opera & Chrome agree with each other (that the [[Prototype]] is unchanged);
Firefox disagrees (it changes the [[Prototype]] to be that it would have
