Prevent recursive resize events in QAbstractScrollArea
During show() of a QAbstractScrollArea we might get resize events, which
results in laying out the children of the scroll area. One of these
children are the scrollbars, and raising them to the top means creating
them, which in turn means creating all parents, including the abstract
scroll area itself. Creating the abstract scroll area means creating
a platform window, which might send synchronous resize events as a
result of creating the window, and we end up recursing.
