Disabled elements don't have `:disabled` or [internals-disabled] matchers added about element-internals-polyfill

Could it be as straight forward as removing the disabled attribute from the MutationObserver filter, and running a callback whenever the attribute changes that toggles the internals-disabled class?

EDIT:

Spoiler alert: it's not as straight forward as that

Note: I tried removing disabled as an attribute in the MutationObserver filter, but it caused the tests to run where the Chrome behaviour is now out of sync with the other browsers.

My thoughts are leading me to believe that Firefox + Webkit aren't setting the :disabled pseudo-class because it should only added to certain form inputs or form-associated elements. Since it sounds like we'll still want to manually apply the pseudo-class, do you have any idea where we might want to do it?

I'm also trying to dive into the Chromium repo to see if I can find anything, but am having no luck.
