Minimal Repro: MedieElement fails on HTTPS

When `MediaElement.Source` is set to a HTTPS-Uri - .NET 4.8 Project throws `NullReferenceException` at System.Windows.Media.MediaPlayerState.OpenMedia(Uri source) at System.Windows.Media.MediaPlayerState.SetSource(Uri source) at System.Windows.Media.MediaPlayerState.Open(Uri source) - .NET Core 5.0 Application sucessfully plays the Source. Plain HTTP works in both runtimes. See https://stackoverflow.com/questions/30702505/playing-media-from-https-site-in-media-element-throwing-null-reference-exception dotnet/wpf#722 fixed and merged with dotnet/wpf#969 into .NET Core.
