On Wayland popup flipping and such is not Firefox's responsibility. Once we've decided the final popup position because the compositor told us, we move the popup to a fixed position, and internally the popup becomes unanchored. Using this boolean to make decisions after the initial popuppositioned event is wrong, so avoid exposing it to JS. Differential Revision: https://phabricator.services.mozilla.com/D142679
