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