+Subject: [PATCH] QTreeView: do not scroll to top if last item is removed
+
+When the last item is the current item and is removed,
+QTreeViewPrivate::updateScrollBars() is called after QTreeViewPrivate's
+viewItems member is cleared. This commit makes sure that viewItems is
+restored by calling QTreeView::doItemsLayout() in this case, preventing
+that the scroll bar range is set to zero temporarily and the view is
+scrolled to the top unexpectedly (this was a regression in 4.7.0:
+QTBUG-13567).
