*Please describe the issue:*

A UIHostingController object presented modally from a UIViewController cannot be dismissed programmatically by means of `presentationMode.wrappedValue.dismiss()`. The UIHostingController is dismissed however if it is pushed rather than presented. See https://github.com/adil-hussain-84/SwiftUIExperiments/tree/master/App2 for a small, minimal UIKit application which demonstrates the problem.

*Please list the steps you took to reproduce the issue:*

1. Initialise a UIHostingController object (which has a SwiftUI root view).
2. Present (modally) the UIHostingController object from a UIViewController.
3. Tap a Button in the SwiftUI view contained within the UIHostingController which calls `presentationMode.wrappedValue.dismiss()`.

*What did you expect to happen?*

The UIHostingController object is dismissed.

*What actually happened?*

The UIHostingController object is not dismissed.


Resolved in Xcode 13.0

This issue is resolved in Xcode 13.0 beta 5. I tested it against an iPhone 15.0 simulator.
