Timeout dialog doesn't read out heading in VoiceOver #387

Open edwardhorsford opened 2 months ago

edwardhorsford commented 2 months ago

I'm doing some quick ad-hoc testing of the timeout dialog in Voiceover on Safari on Mac and iOS.

In both, when the dialog is shown, the paragraph gets read out, but not the heading. My expectation is that the heading should get read out too - at least on first load. Screenshot 2024-07-08 at 15 59 37

Possibly relevant, I note the paragraph gets aria-live="assertive" but the h1 does not.

Hi @edwardhorsford

I just did a quick test with VoiceOver and Safari (Version 17.5). On load it read out "You’re about to be signed out". Is that what is not being announced for you?

Apologies - not had chance to test with iOS.

My understanding for the aria-live="assertive" on the paragraph is to announce the count down when it changes (at 20 second increments).

@shabana-ali For voiceover on Mac and iOS I have not heard it read out the h1.

@shabana-ali Here's a recording of VoiceOver on iOS. The mac was similar.

I've tried various combinations of aria-live="polite" and aria-live="assertive" on the heading, and it never gets read out on iOS if the second paragraph has any form of aria-live. I might suspect this could be a bug with VoiceOver on iOS and multiple aria-live regions.

Thread here on issues with multiple live regions, including this line:

BTW I have also experienced the VO issue where live regions upstage each other completely.

I think this isn't a major bug though - as the paragraph in isolation already gives a clear message about what is going on.

A possible solution would be to make the heading hidden from screen readers, and include the existing heading in the audible message the first time it gets rendered.
