"ARIA required owned elements" (bc4a75): Passed example 3 is incorrect

[kasperisager]

https://act-rules.github.io/testcases/bc4a75/c26f9f87576ea7fbeb2db67a559e78501d1d232a.html

<table role="grid">
	<tr role="row">
		<span role="cell">Item 1</span>
	</tr>
</table>

When parsed as HTML, the above turns into the following:

<span role="cell">Item 1</span>
<table role="grid">
  <tbody>
    <tr role="row"></tr>
  </tbody>
</table>

That code fails the rule due to the row missing a cell.

I also couldn't help but notice that both SortSite, QualWeb, and axe-core pass that case. When I run axe-core directly against the test case, however, it does correctly fail, contrary to what's reported in the implementation data. QualWeb passes it for some reason.

@kasperisager the expectation reads "Each test target only owns elements with a semantic role from the required owned element list for the test target's semantic role."
The row does not own any element. The expectation checks that the owned elements have the required semantic role. Since there are no owned element, I would say the expectation is met.

So, I do think we need to update the expectation to require that the test target owns at least one element.

@carlosapaduarte That's of course entirely correct! We've already implemented the bit about requiring at least one element in Alfa as per #1426 and I missed the fact that the published rule still doesn't include that change.

I'm not so sure we should make them have required children TBH. Is there anything inaccessible about an empty row?

[kasperisager]

Without it, I don't think the rule should exist at all: #1426 (comment)

We should probably only write examples that are correct DOM/HTML. So not an example like that is parsed into a DOM different from what the HTML looks like.
