+<div id="container" role="group" tabindex="-1"></div>

 <canvas id="canvas" tabindex="-1"></canvas>

Do we need the tabindex attribute?

+        // Create an ordinary button on the page, focus it and get its accessibility role.

We are no longer focusing the button. 

+                return expectedButtonRole !== expectedDetachedRole

Missing ;

We do need it just for the <canvas> element to make it focusable via JS to prevent it from being ignored (which this test relies on). I removed tabindex from the <div> and applied your other comments.
