Expected to see the WWDC videos

Hi @jackpal,

Thanks for your detailed bug report.

After some debugging on my side it seems like some "behind the scenes" SwiftUI rendering process stops the WKWebView rendering runtime 🤔

But as of for now I couldn't find any exact reason.
The YouTube iFrame API is correctly loaded and the JavaScript from the YouTube API updates the DOM in the correct way without any errors printed in the JavaScript console.
Additionally, even the didFinish WKNavigationDelegate function is invoked telling that everything was loaded correctly.

When applying a navigationViewStyle modifier with a StackNavigationViewStyle the YouTubePlayers are all shown correctly.

NavigationView {
   // ...
}
.navigationViewStyle(StackNavigationViewStyle())

Closing issue.

Thanks for looking into this! Another work-around (that works for my application) is to remove portrait and upside-down portrait from the permitted orientations of the app.)
