Possibly, and arguably mean that a change that doesn't fire mutation events has 
an effect on what's going on.  Then again, I guess we have that sort of thing 
going on for the "src" attribute of HTMLImageElement, so maybe this isn't a big

Ideally that would trigger the load on its own, without having to do a "foo.type 
= foo.type" hack.

I would be fine with that from a "how easy is it to implement this?" 
perspective, but it introduces hysteresis effects where the state of the DOM is 
not enough to determine what the state of the object is.  I think those should 
be avoided, personally.

I'm not quite sure what you're asking here.
