OverlayViewController is not layout before animation when set before moveOverlay(toNotchAt:animated:)

[denisPoifol]

When setting the viewControllers property just before animating appearance of the overlay :

overlayContainerViewController.viewControllers = [
    mainViewController,
    backdropViewController,
    overlayViewController,
].compactMap { $0 }
overlayContainerViewController.moveOverlay(to: .medium, animated: true)

We end up with the overlayViewcontroller being animated in its height like it should, but also in its width because its view did not layout properly before the begining of the animation.

I could make this work by forcing the layout of the superview of the overlayViewController, but it is a hacky solution, and it would definitely be better if the pod handled this force layout on its own :

overlayContainerViewController.viewControllers = [
    mainViewController,
    backdropViewController,
    overlayViewController,
].compactMap { $0 }
overlayViewController?.view.superview?.setNeedsLayout()
overlayViewController?.view.superview?.layoutIfNeeded()
overlayContainerViewController.moveOverlay(to: .medium, animated: true)
