Implementing audio and video autoplay unlocking

Due to recent changes in the autoplay policy of Chrome 66 developers of interactive experiences on the web are facing new challenges regarding audio and video autoplay. The new policy has unfortunately broken many of the older experiences that rely on autoplaying audio and video.
