The floating window can not back to normal size after maximizing it.

[xiterator]

If we make a DockWidget in a floating and click the fullscreen button (from the demo CMainWindow::createTableWidget ), then
the fullscreen window will not come back to normal size even if we click the fullscreen button again or many times.
It can affect user's experience.

The bug is in the following code:
void CFloatingDockContainer::showNormal(bool fixGeometry)
{
/*
* WindowNoState = 0x00000000,
WindowMinimized = 0x00000001,
WindowMaximized = 0x00000002,
WindowFullScreen = 0x00000004,
WindowActive = 0x00000008
*/

// if (windowState() == Qt::WindowMaximized)   //the bug is here !!!
qDebug() << "CFloatingDockContainer: windowState(): " << windowState();  // it output WindowFullScreen
// Should be changed to the following condition checking, then everything is ok:
if ( (windowState() & Qt::WindowMaximized) != 0 ||
     (windowState() & Qt::WindowFullScreen) != 0)
