I should have thought of that.
That's not entirely true. If the implementation of my-button, let us call it MyButtonElement had the prototype that extends HTMLButtonElement, then the browser can set role=button just fine. > On Jun 13, 2015, at 5:41 PM, Patrick H.

Precisely! I've been saying that for the last two years. It's so nice & refreshing to hear someone making the same argument :) And we (Apple) would love to solve the stylability issue of form elements. - R. Niwa
