That's right.  I was basically testing Alexey's attached test case with
dispatchEvent instead of click(), but it's the same issue discussed here.

It appears that Chrome (i.e., V8), Firefox, and IE restart the dynamic scope
(which V8 calls the "entered context") after a dispatchEvent occurs, but Safari
4 doesn't.  This ends up being visible to the user in a few ways: how relative
URLs are resolved, what the HTTP referer header is set to, and whether an
action is considered a user gesture (perhaps among other things).
