<source onError={callback}> doesn't work

[dmnd]

The error event on <source> elements doesn't work. Looking at #4370, it seems like there is an onError for <video> but I can't tell if that's supposed to work for <source> too.

The error event is useful so I can deduce which format the browser is using.

Do these error events bubble? We might have to attach listeners directly if not (which is what we do for the video & audio elements)

@zpao They don't bubble, so attaching listeners directly seems like the proper way.

Great, and does source have any other events? My quick research only shows error but I suspect load is there as well and probably has the same non-bubbling (basically the same as an img element). I'll try to do some testing but any pointers to specs and whatnot would be helpful.

Hey, guys! This should add onError to the <source>: #5861

[petetnt]

@zpao The spec says that it should follow the resource selection algorithm specified here so it should also support at least loadstart.

[alunyov]

It should, but in fact, it does not support load and loadstart. https://jsfiddle.net/n7sdjh22/
