Bug 1805414 will move menu event handling to the DOM. With that change the current synthetic click behavior of XUL menuitems breaks. On current central, we rely on nsMenuFrame::HandleEvent not getting called at all for synthetic clicks, and instead we just fire a command event synchronously here: https://searchfox.org/mozilla-central/rev/a0d4f8f112c5c792ae272bf6ce50763ddd23ffa2/dom/xul/nsXULElement.cpp#1071 After my patch the command event is fired properly (potentially asynchronously too) by the regular menu activation machinery, which is preferable. * They fire a command event synchronously (even though on some platforms like macOS activating a context menu item is async). * They use a totally different codepath from what a user does. * They don't deal with native menus, etc. We have a proper API for this (activateItem) which takes a much more closer codepath to what users do, requires that the menu is shown, etc. Use that API instead for testing. As a benefit, tests now do not need to close the context menu manually when clicking on a menu item (because we trigger the same code path as users clicking the menu).
