To reproduce:

1. Open test-case.

2.1: Resize the browser both vertically and horizontally until you would have to both scroll both vertically and horizontally to read everything.
2.2: Scroll the page.
2.3: Document "crashes"/goes transparent (aero)

3.1: Resize the browser vertically until you have to scroll the page
3.2: Scroll the page
3.3: Document "crashes"/goes black (including scrollbar)

Closing the tab (ctrl+w) or hitting enter (numerous times depending on how many times the event fired) restores control to Aurora.
It would seem the events fire and the modular alerts open, but clearly something has gone awry.

If I attempt to reload the page at this stage the follow error is reported in the error console:

Error: uncaught exception: [Exception... "prompt aborted by user"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame :: resource:///components/nsPrompter.js :: openTabPrompt :: line 457"  data: no]

Sounds a lot like bug 626963.

Another test case for this bug. It uses a scrolling div control instead of a body scrollbar.

I can no longer reproduce this. It's difficult to resize the window when the alerts steal focu, but that's probably better suited for another bug.

Closing as WORKSFORME.
