[csswg-drafts] [css-typed-om] Should StylePropertyMap methods have CEReactions? (#13892)

kbabbitt has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-typed-om] Should StylePropertyMap methods have CEReactions? ==
I ran into this while fixing a [bug](https://issues.chromium.org/issues/40710238) in which changes to `attributeStyleMap` were not triggering attribute change mutation events. 

Admittedly my understanding here is limited, but from what I've read, it seems like `set`, `append`, `delete`, and `clear` should all have `[CEReactions]`. They can change the `style` attribute, and #200 indicates that anything that can change the `style` attribute should have `[CEReactions]`.
