showing WAI-APG datepicker with code

Hello, When using the aria-selected="true" property on an element with role="gridcell" VoiceOver does not announce the selected state. According to the ARIA 1.2 Spec this is an appropriate implementation of aria-selected.

I created a codepen that uses a slightly modified version of of the W3C WAI APG Datepicker example (https://codepen.io/A11yGreg/pen/wvbZboN). As shown in the following screenshot, aria-selected=”true” is applied to the gridcell of the selected date. I tested VoiceOver on Safari, Firefox, and Chrome and none announce the selected state. This is coded according to ARIA spec and VoiceOver fails to announce the selected state.

Conclusion
For the selected state of a gridcell to be surfaced to VoiceOver users, VoiceOver will have to enable support for this property.

Resources
ARIA spec gridcell is a supported role - https://www.w3.org/TR/wai-aria-1.0/states_and_properties#aria-selected
