Bug 220222 – AX: aria-orientation is ignored on input[type="range"]

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

[Sebastian Silbermann]

`<input type="range" aria-orientation="vertical" />` is exposed as a horizontal slider. IE 11 and Edge 15 they exposed as vertical sliders (verified with JAWS) as defined by spec (Aria 1.1 https://www.w3.org/TR/wai-aria-1.1/#slider + html-aam https://www.w3.org/TR/html-aam-1.0/#details-id-68).

0. Please ignore broken visuals since `input[type="range"]` is not responsible for them. We're only piggy-backing it for input behavior.

1. Visit https://poqq4.csb.app/

2. We refer to `input[type="range"]:not([aria-orientation="vertical"])` as A, `input[type="range"][aria-orientation="vertical"]` as `B`, `input.fix-aria-orientation[type="range"][aria-orientation="vertical"]` as `C` and `[role="slider"][aria-orientation="vertical"]` as `D`

Jaws + {ie11,edge 15}:
  A: left/right slider
  B: up/down slider
  C: up/down slider
  D: up/down slider
Jaws + firefox:
  A: left/right slider
  B: left/right slider (BAD)
  C: left/right slider (BAD)
  D: up/down slider
Jaws + chrome:
  A: left/right slider
  B: left/right slider (BAD)
  C: up/down slider
  D: up/down slider
VoiceOver + (chrome,safari):
  A: left/right slider
  B: left/right slider (BAD)
  C: up/down slider
  D: up/down slider

NVDA: Irrelevant since they don't implement orientation for sliders (https://github.com/nvaccess/nvda/issues/6283).
