This sort of goes against the "registering event listeners should not have side effects" rule, but it's a UI effect the page can't detect so I guess it's ok. This doesn't really work when pages put their event listeners further up the tree, eg. capturing listeners on the document and other "event delegation" tricks, right?
It should work just fine if you check the whole eventtarget chain (from the target to the window object). -Olli
