When you set the interaction control video play, there is also the need to set the interaction control video stop if you want the video to stop. This implies when you show a video in an overlay and the video starts to play you also need to set and interaction to the close button of the overlay control video stop.
We noticed that some users forgot to set this interaction there for we made some minor changes to the interaction to improve the usability.
We made the interaction panel a bit larger so that all the interaction show without the need of scrolling on most screens. Additionally we moved to Media Control directly under the Timeline as these two features are quite often used together.
