rather than the Mouse Down+Up sequence, even if the _OpenOnArrow flag isn't set. This is standard behavior

- Tab Bar: Hide tab item close button while dragging a tab.
- Tab Bar: Keep tab item close button visible while dragging a tab (independent of hovering state).
- Metrics: Various tweaks, listing windows front-to-back, greying inactive items when possible.
