Description

[James Craig]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.4 Safari/605.1.15

Expected results:

a11y: Gecko (and other engines currently) fails computedlabel expectation for <img title="foo" alt="">

Looks like the explicit alt="" overrides the included title attribute.

ARIA WG discussed and agreed this case should pass. WPT test was adjusted to align with the spec.

Looks like the explicit alt="" overrides the included title attribute.

To clarify, isn't that the intention now? That is, for <img alt="" title="foo">, the alt="" should take precedence, cause the img to be pruned from the accessibiliy tree and thus result in a name of ""? That's what the test expects:

<img ... data-expectedlabel="" ...>
