QTableView/QHeaderView incorrect behaviour with moveSection()

The column header of a QTableView is not behaving as expected when the QHeaderView::moveSection() function is used. I have attached a test program that creates and displays a simple table in a QMainWindow. The table is set to single selection mode and row selection behaviour. When a row is selected, the last column header is "not highlighted", but all other column headers are.

If the moveSection() line is commented out, all headers are highlighted as expected.

When this problem occurs, the header will become highlighted if the mouse cursor is hovered over it or the window is moved.
