There's a bug with 3 dots menu button on recommended videos.
img 1 - main page videos have 3dots button, where we can add the scene to the playlist.
img 2 - menu that shows up on 3-dots button click.
img 3 - videos without the 3-dots button.
Steps to reproduce: (Android Chrome)
- click on any video to go to its page.
- on the video page: scroll down to recommendations.
img 1 - main page videos have 3dots button, where we can add the scene to the playlist.

img 2 - menu that shows up on 3-dots button click.

img 3 - videos without the 3-dots button.
