Closed state of QDockWidget not restored by QMainWindow::restoreDockWidget

The following piece of code results in all dock widgets being visible after the call to restoreDockWidget, even though they were hidden when QMainApplication::saveState was called:

restoreState(state.toByteArray());
// Dock widget gets created
...
restoreDockWidget(dockWidget);

Unknown macro: {/quote}

On the other hand, the following works as expected, with dock widgets remaining invisible if they were hidden when the state was saved:

// Dock widget gets created
...
restoreState(state.toByteArray());

I see no reason why restoreDockWidget would have a different behavior, forcing users to manage the visible state of dock widgets themselves, hence this bug report.
