Fix conflict between QMainWindow::restoreState() and QWidget::setStylesheet()
If QMainWindow::restoreState() then QWidget::setStylesheet() were called
before the QMainWindow is shown, the size of QDockWidget can not be
restored.
QWidget::setStylesheet() will generate QEvent::StyleChange event, which will
cause the function QDockAreaLayout::fitLayout() to be called before the layout
of MainWindow is activated. Although the state info has been stored in
a QMainWindowLayoutState variable by QMainWindow::restoreState(), but
QMainWindowLayout::setGeometry() still isn't called at present. So
QDockAreaLayout::fitLayout() will force the size of dockwidgets
and centralwidget to be calculated using the wrong geometry, which will
break the state restored by QMainWindow::restoreState().
This is a side effect of 692e9103ebb85b90e79377206d5d03b704d43d42.
