On ToT WebKit, Gmail no longer loads properly. Even if it loaded, it doesn't handle clicking and other events properly.
I can't tell whether this is a regression in loader (XHR?), JSC, or event handling. The fact page doesn't finish loading seems to suggest some regression in loader but when it loads, I can't interact with the page properly (CSS styles seem to work properly) so I'm also suspecting JSC regression. However, gmail relies heavily on XHR so it's possible that user interactions are prevented due to some bugs in XHR.
Okay, this regression still exists in r90643.
Can we get a tighter regression range?

I'm building r90594 because I suspect that http://trac.webkit.org/changeset/90595/ is the cause.
It was not r90595.
Testing with our archive builds says that it's r90602 indeed.

I have confirmed this on my local build as well.
+eae since he knows how gmail works.

This should be fixed in r90673 - reverting the changes that look like they are to blame.
