Bug 162269 – AX: aria-pressed state not correctly conveyed to VoiceOver iOS on <button> unless role=button added

• Status: RESOLVED
• Resolution: FIXED
• Component: Accessibility

[Paul J. Adam]

Overview:
When aria-pressed is set on a native HTML <button> element the state is not conveyed to VoiceOver iOS 10, however, if the extra role="button" attribute/value is added to the <button> tag, e.g. <button aria-pressed="true" role="button"> works but <button aria-pressed="true"> does not work. 

Steps to Reproduce:
1. Turn on VoiceOver on iOS 10.
2. Visit http://pauljadam.com/demos/button.html in Safari iOS
3. Activate the aria-pressed button example under the aria-pressed heading.
4. Notice that aria-pressed button is now visually styled to look pressed and the aria-pressed attribute has been updated to equal "true". 
5. Set VoiceOver focus to the newly pressed button.

Expected Results:
VoiceOver speaks "aria-pressed Toggle button Pressed Double tap to toggle setting."

Actual Results:
VoiceOver speaks "aria-pressed Toggle button Not pressed Double tap to toggle setting."

Additional Information:
The second aria-pressed role iOS bug button works properly because the extra aria-pressed="true" attribute/value is added.
