Nat, Boris, we reconsidered this issue during today's call following the email from Boris at http://lists.w3.org/Archives/Public/public-web-perf/2013Feb/0036.html [[ Seeing that requestAnimationFrame is using the Page Visibility definition of visibility, at this time we don't believe we should expand requestAnimationFrame to include iframe visibility. As CSS properties can be queried through script, we don't feel that this is a missing piece. We are interested in further investigating an element visibility that can query the visibility state of elements on the page (e.g., subdocuments, images, canvases, etc.). In rAF L2 spec, we can possibly reference the element visibility instead of page visibility. We can schedule a future conference call to discuss element visibility in more detail. ]] http://lists.w3.org/Archives/Public/public-web-perf/2013Apr/0032.html As such, no further change will be made to the specification. Let us know if you're dissatisfied by the outcome and would like to object. Thank you, Philippe
