1817042 - Collect telemetry on how long originating tabs are in the background, and how long they're in the foreground

Status: RESOLVED FIXED

(Toolkit :: Picture-in-Picture, task)

Description

[Mike Conley (:mconley) (:⚙️)]

Product is curious about how often users stay on the same tab on which they've already PiP'd out a video. They want to know if these sorts of tabs tend to stay more in the background, or be in the foreground.

Notably, we cannot use visibilityState or detect whether or not the window is occluded,
as we currently force the platform to keep any windows that are PiP'd as "visible" in
the platform layer in order to keep things like subtitles working properly. So this
really only measures the time in the foreground of tabs, but cannot tell if the user
foregrounds a completely separate application to occlude the originating window.
