menu item and instead close the menu (which clickButton now warns about).
There doesn't appear to be a way to reliably detect and hence wait for these events.
We also can't disable the enter transition because the menu doesn't exist until the
right click event, by which point the transition has also already started.
We tried an environment variable to allow the test to disable them before they start,
but it was still flaky. So we now simply click the menu item programmatically for menus
with enter transitions.
