When a media element is removed from a Document, the user agent must
run the following steps:
1. Asynchronously await a stable state, allowing the task that removed
the media element from the
Document to continue. The synchronous section consists of all the
remaining steps of this algorithm.
(Steps in the synchronous section are marked with.)
2. If the media element is in a Document, abort these steps.
3. If the media element's networkState attribute has the value
NETWORK_EMPTY, abort these steps.
4. Pause the media element.
This seems to reflect the current webkit behavior. The element is paused
when it's removed from the Document.
I'll focus on the bug report I'm putting together.
function example() {
var a = audioElement.parentNode.removeChild(audioElement);
a.play(); // there is an audible pause.
};
This, per spec, should cause the element to be paused. See step 1 above.
a.play() will run before the algorithm reaches step 4. Currently you would
need to wait for the "paused" event and play() from there. We could change
the spec so that play() sets a flag on the element that the algorithm
above checks before pausing the element, or some such, to make the above
do the intended.
