Bug 255621 – AX: role updates from HTML-AAM WPT failures

• Status: REOPENED
• Component: Accessibility

[James Craig]

HTML-AAM role tests landed in WPT yesterday.
https://wpt.fyi/results/html-aam/roles.html?label=master&label=experimental&aligned
(Expand the "show details" switch if needed)

Compare to the HTML-AAM spec here: https://w3c.github.io/html-aam/

I think most of the "generic" vs "" are already resolved in the nightlies, but there are a few others remaining. Trying to list those here.

# aside/footer/header

WebKit maps these correctly in one context but not another. See differences where these are scoped to the body or main versus other contexts. Examples: 

- https://w3c.github.io/html-aam/#el-aside
- https://w3c.github.io/html-aam/#el-footer
- https://w3c.github.io/html-aam/#el-header


# address/details/menu (should be group)

- https://w3c.github.io/html-aam/#el-address 
- https://w3c.github.io/html-aam/#el-details 
- https://w3c.github.io/html-aam/#el-group 


# orphaned li (outside a list)

- returning listitem; should be generic


# dfn/dd/dt (term/definition)

Might be resolved in nightly, along with others (em/strong/i/b/s/etc)?

Reopened as the PR addresses a few of the needed fixes (address and fieldset), but not all.
