REVISION SUMMARY
If several buttons share an edge, i.e. spacing between decoration
buttons is set to 0, and the pointer is on that edge, both buttons will
be hovered.
This happens because QRectF::contains returns true for points that are
on "outer" edges, e.g.
QRectF rect(0, 0, 10, 10);
rect.contains(QPointF(10, 5)); // returns true
TEST PLAN
Manually.
