QTableView::doItemsLayout() updated the scroll offset for the vertical
header after layouting was done. Since the scroll offset affects the
viewport of the editors, the adjustment was done too late.
Therefore we update the scroll offset right after the scrollbars are
set inside QTableView::updateGeometries()
