Is this a use case for visibility, or focus? Focus is also important (not
sure if the fairly ubiquitous window focus events remain unspecced), but
For clarity, I've included the current draft of the proposal below, which
incorporates the feedback from this thread.
There is currently no good way for a web page to detect that it is
completely invisible to the user (for example, that it is a background tab),
although some imperfect heuri
