| 2754 | * in that they only get called from the controller (in |
| 2755 | * nsDOMWindowController::IsCommandEnabled). The actual construction of the |
| 2756 | * context menus in communicator (nsContextMenu.js) has its own, redundant |
| 2757 | * tests. No big deal, but good to keep in mind if we ever clean context |
| 2758 | * menus. |
