+<!--
+  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.
