Reproduction steps

This works:

val extras = Bundle().apply { putString("uri", uri) }
val mediaMetadata = MediaMetadata.Builder()
    .setDisplayTitle(title)
    .setExtras(extras)
    .build()
val mediaItem = MediaItem.Builder()
    .setUri(uri)
    .setMediaMetadata(mediaMetadata)
    .build()

override fun onMediaItemTransition(mediaItem: MediaItem?, reason: Int) {
   println(mediaItem?.mediaMetadata?.extras?.getString("uri"))
   // NOT null
}

This doesn't work (when only setExtras are used):

val extras = Bundle().apply { putString("uri", uri) }
val mediaMetadata = MediaMetadata.Builder()
    .setExtras(extras)
    .build()
val mediaItem = MediaItem.Builder()
    .setUri(uri)
    .setMediaMetadata(mediaMetadata)
    .build()

override fun onMediaItemTransition(mediaItem: MediaItem?, reason: Int) {
   println(mediaItem?.mediaMetadata?.extras?.getString("uri"))
   // null
}

Same issue with playlistMetadata.

Expected result

MediaMetadata extras should not be null.

Actual result

MediaMetadata extras are null.

I am observing this issue for all mp3 files (not tested for other types).
