UI/Qt: Collapse hover-expanded vertical tabs after leaving window

Browse source 
When collapsed vertical tabs are expanded on hover, the collapse check
used QCursor::pos() against the vertical tabs rect. On some platforms,
after the cursor leaves the browser window entirely, that position can
remain at the last in-window coordinate, so the tabs stay expanded.
