// One simple case to ponder if: window A has a toggle to create windows B/C/D. Dock B/C/D together, clear the toggle and enable it again.
// When reappearing B/C/D will request focus and be moved to the top of the display pile, but they are not linked to the dock host window
// during the frame they appear. The dock host window would keep its old display order, and the sorting in EndFrame would move B/C/D back
// after the dock host window, losing their top-most status.
