Bug: args.Cue in NativeAOT-build has IInspectable type

Description

When custom handling subtitles in MediaPlaybackItem in UWP on .NET 9, the argument type changes to WinRT.IInspectable in NativeAOT build.

This code in Debug build outputs ImageCue (in the case of my video file, which is correct), and when built in NativeAOT it starts outputting IInspectable.

private void CurrentSubtitle_CueEntered(TimedMetadataTrack sender, MediaCueEventArgs args)
{
    RunOnUIThread(() =>
    {
        DebugText.Text = args.Cue.GetType().Name;
    });
}

Steps To Reproduce

1. Create MediaPlaybackItem object with videofile with subtitles
2. Select TimedTextTrack from embedded subtitles
3. Subscribe to its CueEntered event
4. Output somewhere type of args.Cue in CueEntered event handler

Expected Behavior

args.Cue has the same type in NativeAOT build as in debug-build.

Version Info

.NET: 9.0.7
CsWinRT: 2.2.0
Windows SDK: 10.0.26100

Additional Context

No response

Start by reproducing the MediaPlaybackItem subtitle CueEntered scenario described in the issue under both Debug and NativeAOT builds, using the reported .NET, CsWinRT, and Windows SDK versions. Trace the projected MediaCue handling and compare args.Cue types; done means NativeAOT reports the same cue type as the Debug build.
