--- Comment #2 from Tyler Wilcock <tyler_w at apple.com> ---
I believe this is because the children of buttons are presentational, i.e. not supposed to be exposed by the user agent.

https://www.w3.org/TR/wai-aria/#button

This behavior is implemented here:

https://github.com/WebKit/WebKit/blob/b86ae1a3bfa93a5cb1359c3370a32a3adeb5507e/Source/WebCore/accessibility/AccessibilityNodeObject.cpp#L489

Firefox matches our behavior, Chrome does not (it exposes the heading). I do understand the usecase...maybe worth starting a discussion on https://github.com/w3c/aria/issues?
