QWidget::mousePressEvent is documented to implement the closing of
popups if the widget is a popup. QAbstractScrollArea is one of the
QWidget subclasses that might be used as a popup as well, so instead of
just ignoring mousePressEvents, pass the event on to the QWidget
implementation for regular popup handling.
