This comes back to bug 42557 and co. It only does something half-reasonable on Windows (on macOS we just lie and make z-order tracking be latest-active tracking), and given we don't use the special zorder flags elsewhere I'm pretty sure we should be able to just rip this off... On some DEs like Wayland we can't re-stack toplevel windows. Differential Revision: https://phabricator.services.mozilla.com/D213602
