Thats not the root cause. Its just that the problem is triggered by
mouse down click, but in general it shouldnt make a different whether
thats mouse down or up or click. Its probably just easier to reproduce
with one of those methods than the other.
The root cause as of now seems to be the asynchronous creation of menu
popup frames in the gecko engine. Somehow the click event gets
redirected to a not yet created frameset which seem to trigger a click
on a random menu entry because the menu items are not yet properly
mapped to screen.
