Description

The goal of this new permission policy is to have a mechanism to allow embedder documents to limitedly control embedded iframe media playback based on whether the embedded iframe is rendered or not. That is:

• When the iframe is not rendered, the embedder is able to pause the iframe media playback; and
• When the iframe becomes rendered again, the embedder is able to resume the iframe media playback.

There is some discussion happening in https://github.com/whatwg/html/issues/10208. This feature development in Chromium is being tracked on https://chromestatus.com/feature/5082950457884672.
