[Problem/Bug]: WebView2 Fixed Runtime does not support PlayReady functionality.

What happened?

We're encountering an issue where the WebView2 Fixed Runtime does not support PlayReady functionality. Applications such as ours (Cider) that rely on PlayReady DRM for media playback experience compatibility problems when using the WebView2 Fixed Runtime. This lack of support results in failures to play protected content as expected.

Currently, this limitation is impacting our ability to provide secure media playback within our application. We need PlayReady support in the WebView2 Fixed Runtime to ensure compatibility with our DRM requirements and maintain a consistent user experience.

Importance
