I like to put the per-spec bits first, so [Unscopeable, RaisesException,
CustomElementCallbacks]. Do you know why [CustomElementCallbacks] is needed
here?

Also, all new bits need to be [RuntimeEnabled=something] to avoid shipping it.

Done.
I think, It will result in an element being inserted, so It could enqueue a
Custom Element callback. Tagging with CustomElementCallbacks will invoke the
callbacks before returning to script. right?
Added, RuntimeEnabled=DOMConvenienceAPI. Thanks.
