What are the expected results of the browsers after changing the test this way? Is Webkit the only engine that implements the specification order right now?

What are the expected results of the browsers after changing the test this way? Is Webkit the only engine that implements the specification order right now?

The expected order of the events for autoplay media is according to specification:

• canplay, canplaythrough, play, playing

The most of major browsers doesn't follow the specification (except Safari, but it has another issue which is affecting final results)

Chromium:

• canplay, play, playing, canplaythrough (see here)

The expected results after changing the test: 10/10 -> 6/10

Firefox:

• canplay, play, playing, canplaythrough (see here)

The expected results after changing the test: 10/10 -> 6/10

Safari:

• canplay, canplaythrough, play (missing), playing (see here)

The expected results after changing the test: 4/10 -> 4/10 because the play event is missing in expected event order, so no changes in results, while canplaythrough event is on this place.

FAIL message: assert_array_equals: expected property 2 to be "play" but got "playing" (expected array ["canplay", "canplaythrough", "play"] got ["canplay", "canplaythrough", "playing"])

There was discussion about the event ordering - WICG/interventions#23 (comment)

Ok, changing the test to reflect the current specification seems like the right choice. Whether the specification should be changed to reflect the actual browser implementations is probably also worth a discussion somewhere else!
