tst_QWindow::positioning() fails on Mac OS X

The fullscreen transitions in this test function cause a Cocoa warning and a test failure:

2012-06-06 11:21:16.627 tst_qwindow[42211:703] not in fullscreen state
FAIL! : tst_QWindow::positioning() Compared values are not the same
Actual (originalPos): QPoint(0,1010)
Expected (window.pos()): QPoint(0,0)
Loc: [tst_qwindow.cpp(198)]

When this happens, isActive() also fails:

FAIL! : tst_QWindow::isActive() Compared values are not the same
Actual (window.received(QEvent::Resize)): 4
Expected (1): 1
Loc: [tst_qwindow.cpp(255)]

Note that isActive() does not fail if positioning() is skipped.
