michael@0	10	<!--
michael@0	11	This test checks that popup elements can be removed in various ways without
michael@0	12	crashing. It tests two situations, one with menus that are 'separate', and
michael@0	13	one with menus that are 'nested'. In each case, there are four levels of menu.
michael@0	14
michael@0	15	The nextTest function starts the process by opening the first menu. A set of
michael@0	16	popupshown event listeners are used to open the next menu until all four are
michael@0	17	showing. This last one calls removePopup to remove the menu node from the
michael@0	18	tree. This should hide the popups as they are no longer in a document.
michael@0	19
michael@0	20	A mutation listener is triggered when the fourth menu closes by having its
michael@0	21	open attribute cleared. This listener hides the third popup which causes
michael@0	22	its frame to be removed. Naturally, we want to ensure that this doesn't
michael@0	23	crash when the third menu is removed.
