Follows whatwg/html#2530. As explained there, the circumstances in which this would actually be fired by the UA are not tested in this PR, waiting instead for #5003. As a side effect this syncs various IDL snippets with the HTML Standard.

The messageerror event is used when deserialization fails. E.g., when an ArrayBuffer object cannot be allocated. This also removes StructuredCloneWithTransfer as deserializing errors now need to be handled on their own. Tests: web-platform-tests/wpt#5567. Service workers follow-up: w3c/ServiceWorker#1116. Fixes part of #2260 and fixes #935.

I'm curious about this test -- if I try the same thing with onmessage and message instead, it doesn't fire on Chrome or Firefox. Is there something special about the messageerror event here? Or am I missing something?
(BTW, it works fine if the event is dispatched on window instead of document.body)

If it doesn't work with message, that's likely a sign this test is bad. I'll look into it first thing on Monday. The fix might indeed just be dispatching on window.

This test appears to be just invalid, yeah. I'll submit a PR removing it.

This is a follow-up to #5567. As pointed out in https://github.com/w3c/web-platform-tests/pull/5567/files#r114040410, this test is invalid. messageerror (and message) have their corresponding event handler content attributes on document.body, but with the actual event handler belonging to Window.

This event is not currently wired up anywhere, but will be used in a subsequent CL. The idea is that when posting a message that cannot be decoded by the receiver, the receiver will dispatch a messageerror event instead of a message event.
