YouTubePlayerSupportFragment inside NestedScrollView with bottom-sheet behaviour scrolling on its own

Question

YouTubePlayerSupportFragment inside NestedScrollView with bottom-sheet behaviour scrolling on its own after youtube onLoaded() is called.

YouTubePlayerSupportFragment scrolling the bottom-sheet up and onLayoutChild() method is called in BottomSheetBehavior.

public boolean onLayoutChild(CoordinatorLayout parent, V child, int layoutDirection )

If I return simply from onLayoutChild() i.e returning true directly, in MyBottomSheetBehavior, video doesn't play and static image is shown in youtube_view like thumbnail image without any video control views like play/pause, fullscreen views etc.

Have a look below:

Find my code below to initialize the youtube player:

val youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance()
    //Initialize YouTube Player
    youTubePlayerFragment.initialize(DEVLOPERKEY, object : YouTubePlayer.OnInitializedListener {
        override fun onInitializationSuccess(provider: YouTubePlayer.Provider, youTubePlayer: YouTubePlayer, b: Boolean) {
            //youTubePlayer.setFullscreenControlFlags(0);
            isInitialize = true
            mYouTubePlayer = youTubePlayer
            mYouTubePlayer.cueVideo("videoId")
        }

        override fun onInitializationFailure(provider: YouTubePlayer.Provider, youTubeInitializationResult: YouTubeInitializationResult) {
            isInitialize = false
            player = null
        }
    })
    val transaction = supportFragmentManager.beginTransaction()
    transaction.add(R.id.youtube_view, youTubePlayerFragment as Fragment).commit()
