We would enable the ability to control media when only the page has audible media at least once time [1]. The recommended way of determining the active media session in the spec [2] is also depending on the audio focus, which would be claimed by the window when the window becomes audible.
So if you unmute you video, then you can receive the media key since then, even if the media gets muted again.
