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.

And, I would posit, any scripting that was done to act on the all-singing, all-dancing new web component button (if it does anything more than a regular button) would not work for the fallback. Unless it's really just using web components for fancy styling (for instance having a "material design" button that essentially still works just like a button) - in which case, it makes more sense to work on stylability of standard elements. 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
