key_equivalents_run_through_the_normal_shortcut_path_once failed about one
full ui-egui run in four ("the menus weren't read again", 5 vs 4). Each
app mirrors its shortcut overrides into a process-wide store every frame,
bumping shortcut_editor::GENERATION, and the plug-in registry's revision is
process-wide too. Tests running alongside with other shortcuts flip them,
which rightly makes the menus read again. The test now checks two idle
frames during which those generations held still (trying up to 50 times),
so it still fails if idle frames re-read the menus on their own.
