KDE in F34+ is now placing sleep, restart and shutdown buttons
right on the system menu, not in a submenu. So we need to sort of
tweak this logic. The approach here is: we count the GNOME
submenu as both a "power" and "leave" menu, so the needle to
enter it has both tags. KDE still has a "leave" submenu, but the
power options are not in a submenu any more, so the new "leave"
needle only has the leave tag, not the power tag. For "leave"
actions we just unconditionally expect the "leave" tag; for
power actions we first match on *either* the submenu tag (for
GNOME and earlier KDE) *or* the action tag, click whatever we
found, and then if we matched the submenu (not the action), we
assert and click the action. After that all paths should be in
sync again and we can continue.
