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