1877875 - Don't expose children of role="img" to clients

Status: NEW

(Core :: Disability Access APIs, defect)

Description

[James Teh [:Jamie]]

STR (with NVDA):

1. Open this test case:
   data:text/html,<button>before</button><div role="img" tabindex="0" aria-label="label"><p>content
2. Tab to the div.
   • Expected: NVDA should say: "label graphic"
   • Actual: NVDA says: "label content label graphic"

This is partially due to buggy NVDA behaviour. However, the ARIA spec says that role="img" should have presentational children, so we really shouldn't be exposing them anyway, and correcting that fixes the problem for NVDA users.
