--- Comment #2 from Dimitri Glazkov <dglazkov@chromium.org> ---
I think it was Boris who came up with this.

http://dev.w3.org/csswg/selectors4/#type-selectors

In order for <x-button> (a subclass of HTMLButtonElement) to also match UA
styles for <button>, we redefine "element type" to mean:

1) the element itself -- x-button
2) all types it is inherited from -- button.
