Future tightening to separate Document and Element paths might be beneficial.

I’ll have to fix that event listener sidebar test failure. Seems like I made some mistake in the inspector part of this.

Oops. Forgot to fix that!

Good idea. I’ll do that later.

This looks like it may have caused a 2.5%+ regression on html5-full-render on ML on perf.webkit.org:

Ouch! Well, I assume we can get that speed back with inlining.

[Darin Adler]

Which might or might not undo the shrinking.
