New issues with vnu-jar 21.10.12

Just tried updating locally to see if it was a simple upgrade, and got the following new issues

Here are the unique rules:

• error: The “role” attribute must not be used on a “tr” element which has a “table” ancestor with no “role” attribute, or with a “role” attribute whose value is “table”, “grid”, or “treegrid”.
• info warning: Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).

• info warning: The “contentinfo” role is unnecessary for element “footer”.

@sideshowbarker I think the treegrid parsing might be an upstream issue. It looks like the parent table does have the correct role, but it might be tripping up on the intermidiate <tbody>

[sideshowbarker]

@sideshowbarker I think the treegrid parsing might be an upstream issue.

Upstream where?

[nschonni]

Sorry, I mean in the Validator project. I was pinging here before opening an issue there, if you think the error is correct rather an a parsing issue

[sideshowbarker]

Sorry, I mean in the Validator project.

Aha — sorry, my fault for not having seen where this issue was raised 😄 I thought it was in the validator repo…

I’m not sure yet — haven’t made time yet to investigate

[ZoeBijl]

It seems as though the error is correct? The treegrid example has <table role="treegrid"> and <tr role="row">. According to ARIA in HTML the <tr> shouldn’t have that role? The validator is merely showing that?

Am I misunderstanding the issue?

Digging a bit further:

<table role="treegrid"><tr role="row"><td>test</td></tr></table> results in:

error: The “role” attribute must not be used on a “tr” element which has a “table” ancestor with no “role” attribute, or with a “role” attribute whose value is “table”, “grid”, or “treegrid”.

If you remove the role from the <tr>, like so:

<table role="treegrid">
  <tr aria-level="1" aria-posinset="1" aria-setsize="1" aria-expanded="true">
    <td>Test</td>
  </tr>
</table>

the validator throws this error:

Element tr is missing one or more of the following attributes: role.

Looking at the ARIA in HTML I think this last example should pass?

---

Additionally, in the datepicker example nu validator detects a missing aria-checked attribute. The design pattern calls for an aria-selected (which is present)—it was added to the example in this commit.

"file:/home/runner/work/aria-practices/aria-practices/examples/dialog-modal/datepicker-dialog.html":147.65-148.78: error: Element “td” is missing one or more of the following attributes: “aria-checked”, “role”.

I’m not sure how nu validator works or how the checks are performed/updated. But it seems like there are some clashes?

@jongund will file the bug to validator.

ARIA Principle is "Therefore, authors MUST NOT apply aria-expanded, aria-posinset, aria-setsize, and aria-level to a row that descends from a table or grid, and user agents SHOULD NOT expose any of these four properties to assistive technologies unless the row descends from a treegrid."

In other words, aria-expanded, aria-posinset, aria-setsize, and aria-level to a row is allowed at Treegrid.

[jnurthen]

From the Spec:
While the row role can be used in a table, grid, or treegrid, the semantics of aria-expanded, aria-posinset, aria-setsize, and aria-level are only applicable to the hierarchical structure of an interactive tree grid. Therefore, authors MUST NOT apply aria-expanded, aria-posinset, aria-setsize, and aria-level to a row that descends from a table or grid, and user agents SHOULD NOT expose any of these four properties to assistive technologies unless the row descends from a treegrid.
