Single-window mode popups and edited scene windows fixes.
Fix single-window mode popup not closing when OptionBox is clicked.
Fix single-window mode submenus closing when parent menu item, that was used to open it is clicked (using same safe-area logic as platform specific code).
Disallow windows that are part of an edited scene from being set as exclusive or popup to prevent it from locking up the editor.
