Bug 25132 – help prevent crash in chromium event handling

• Component: DOM
• Status: RESOLVED FIXED

[Antony Sargent]

This is some cleanup motivated by the  crash in http://crbug.com/9775 , which happens because of calling window.open inside a window.onload handler. 

These changes are just part of the fix, along with some asserts to help prevent breakage on future changes. 

Patch forthcoming. (I will also be adding a layout test for this in a separate patch.)

We usually indent these to the same col as "Reviewed By".

TODO(asargent) -> FIXME:in WebKit world.

no brackets around one-liners.
