First pass at tests for whatwg/html#2373. What else would y'all like to see, @annevk, @arturjanc, and @zcorpan?

This all looks resaonable to me. Wouldn't getComputedStyle be an easier way to test CSS? Or did you specifically want to test that event? It seems with that event you don't know if it failed if the browser decided not to fetch the image for some other reason.

Ah, I didn't think about getComputedStyle. :) That's simpler.

Updated the last test to use getComputedStyle. Not sure if the requestAnimationFrame is necessary; I have no idea what the timing of CSS style resolution/application is in relation to the current JavaScript task...

getComputedStyle forces style resolution, but the loading of background images is not deterministic, so that event might never fire I suppose.

(Does it fire on time in browsers today?)

It doesn't. :( I'll drop the event. It's just going to be flaky even if it works, and the getComputedStyle bit is good enough in itself.

No need for rAF. Can just make this a sync test().

I think the above two should be asserted directly after document.head.appendChild(s);

Assert pre-insertion IDL and content attribute here?

This is now #21853. I didn't address @zcorpan's nits though and they still seem valid...
