GlobalEventHandlersEventMap "command" mapped incorrectly

[jpc-ae]

Command events fire a CommandEvent, however they are currently mapped to the basic Event interface.

Ref:

At the moment, I need to assert or put a guard clause to get correct typing inside a command event handler. Please update the type mapping under GlobalEventHandlersEventMap.

Hello Jason P. Cochrane (@jpc-ae),

I don't think this is an issue with the DOM lib generator itself. GlobalEventHandlersEventMap is generated from upstream WebRef data, and oncommand is defined as a generic EventHandler in the IDL.

If the command event should be typed as CommandEvent, the upstream WebRef data/spec mapping would likely need to be fixed first.

I'm not completely sure yet whether the upstream mapping is actually incorrect, though, so I think that should be verified before treating this as a generator issue.

At least according to the WHATWG spec (https://html.spec.whatwg.org/multipage/indices.html#events-2) oncommand (the command event) fires a CommandEvent. If it didn't, you wouldn't be able to access ev.command which is arguably one of the most important properties of the fired event.

Would https://github.com/w3c/webref be the place to file an issue then? Or would it be even further upstream from there?

Not sure, but you can check there and make sure the isssue is from there

Hmm, as far as I can find, upstream is correct. Unless I'm looking in the wrong place? https://github.com/w3c/webref/blob/a0506ac035dfcb3c1e6c0be9127be0b28f15a534/ed/events/html.json#L638

You are looking at the right place i am not sure

Maybe the CommandEvent is not recognized by this generator and it falls back to Event? At the very least, it does seem like I've filed this in the right place.
