Dismissing a landscape presented window doesn't return outgoingWindow orientation.

[markst]

If I present a window with a root view controller which forces landscape orientation:

- (UIInterfaceOrientationMask)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeRight;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}
- (BOOL)shouldAutorotate
{
    return YES;
}

Upon dismissing the window:

[TTWindowManager.sharedInstance dismissTopWindowWithCompletion:NULL]

The outgoingWindow orientation remains landscape & I can't return the orientation back to portrait.

I'm trying to reproduce the issue with the demo project.
This is pretty much what I'm experiencing:

Removing the backgroundAnimationWindow seems to improve this issue.
