Description

AVT 3 - Slider status numbers are announced incorrectly with VoiceOver and not announced at all with JAWS. The number input field is announced as a stepper which makes it difficult to understand the field that is focused.

The example should follow the keyboard interaction and ARIA attributes outlined in the ARIA Authoring Practices Horizontal Slider Design Pattern.

@dakahn Retested with VoiceOver and this is still an issue for the Vanilla component.

@snidersd tested in the VoiceOver in Safari and it seems like VO is maybe bugged?

Testing the WAI-ARIA example and the controls for moving the slider don't work and the slider itself reads poorly. Tested with JAWS and seems pretty great? Can you confirm?

[snidersd]

@dakahn I tested VO on macOS with Safari and Chrome and get the same results. JAWS works for both the Carbon React Component. I also tested the ARIA slider example with VO and Safari on iOS and it works, but it does not work with the React Carbon slider, so I can't confirm that its VO or an issue related to the macOS.

Marking as blocked until we can confirm where the underlying issue resides. Also ran into what @dakahn mentioned in VO on Safari:

Procedure

1. Navigate to Slider
2. Press Control+Option+Shift+Down Arrow
3. Press Control+Option+Right Arrow

Expected: Slider to increment value
Actual: Slider value remains the same

It seems like this might be a bug on Safari's end. Using the WAI-ARIA slider example as a neutral test case we see the same problem (unable to move slider and have number read reliably). There's a bug filed in the Webkit bug tracker we'll watch for updates.
