1721390 - aria-expanded on buttons and links with voiceover does not report expanded

Status: VERIFIED FIXED

(Core :: Disability Access APIs, defect, P1)

Description

[Bryan Rasmussen]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:90.0) Gecko/20100101 Firefox/90.0

Steps to reproduce:

I downloaded the latest version of FF, this was on Apple M1 with Big Sur.

I made a document with a button or a link with aria-expanded="true" attribute on it. It is not reported as being expanded, same problem if it is aria-expanded="false" it is not reported as being collapsed.

Actual results:

When I tab to the button or navigate to the button with Voiceover - VO-next arrow it reads that I am on a button but it does not tell me if it is expanded or collapsed.

Expected results:

Voiceover when reading the button with an aria-expanded true or false should read the exanded stated - expanded or collapsed.

Sure, here https://codepen.io/bryanrasmussen/pen/RwVxMKB which is adapted from https://www.w3.org/WAI/GL/wiki/Using_the_WAI-ARIA_aria-expanded_state_to_mark_expandable_and_collapsible_regions#Example_1:_Using_a_button_to_collapse_and_expand_a_region
however the following will also work
https://codepen.io/bryanrasmussen/pen/gOWoGJK

My understanding is that when you come to a button with aria-expanded = true the screenreader should announce expanded and when it is aria-expanded = false it should announce collapsed. In the case of VoiceOver with Firefox it says something like (for the second example)

1. Test button, button
2. You are currently on a button in a frame (because codepen) etc. etc.

there is no collapsed or expanded information added.
