I agree in principle, Dmitry.  Ideally we would not fire any events at a page
behind a modal dialog.  However, it makes sense to change this in smaller,
isolated changes just in case there's a web compat issue.  In particular
special casing focus/blur makes sense in the short term for the following
reasons:

- This case is causing ASSERT failures on a very popular webpage (gmail).  I
don't know of any popular sites that trigger ASSERT failures on other events
(like onmessage).
- The blur event always fires when a modal dialog is opened up since the modal
dialog will gain focus.  This makes it much more likely to trigger bugs than
things like onmessage which are racy.
- The behavior in this patch matches a released browser (Safari 4.0.4), which
reduces the change of introducing new compat bugs.

Also this patch is quite tiny and doesn't touch anything as sensitive as the
core event handling logic.
