Content sgtm. The wording might be improved. Maybe something like: "then the user agent may also run the following substeps immediately or wait until [...]"? |

There was a problem hiding this comment.
Remove class="note" -- this paragraph defines a term and has requirements. :-)

This was trickier than expected with the event order, but I gave it a shot in 5cc7b99. @xxyzzzq, can you add that to your branch for easier reviewing? Can everyone including @xxyzzzq review the sum of changes to see if this makes sense? Discussion about event order in WICG/interventions#23. |

Starting autoplay when media elements loaded is too agressive. Added supplementary saying that the user agent may delay autoplay until video elements become visible.

Pushed as 8ebd581, I had to add a reference back to this PR in the commit message but the source change is the same. There is one thing that's still needed, and that's to look for event order tests in web-platform-tests and update them, or to write them if they don't exist. Any takers? |
