[Accessibility] accessibility checker to flag H1..H6 inside a table header block

[HaiderAli]

Using the RCE It is possible to place a heading (e.g. “h1” .. “h6”) block inside a table header cell. This generates HTML like the following (example) snippet:

<tr>

<th>

<h4>SECTION</h4>

</th>

<th>

<h4>INSTRUCTIONS</h4>

</th>

<th>

<h4>IMAGES</h4>

</th>

</tr>

This fails WCAG SC 4.1.1 (Parsing). When there are errors in the grammar/syntax of any markup, it cannot be reliably guaranteed that Ats (like screen readers) or other user agents will render that markup as intended.

Currently the “accessibility checker” in the RCE does not flag the presence of headings inside table header cells as an accessibility issue for authors to remediate.

We request that the “accessibility checker” in the RCE flag the presence of headings inside table header cells as an accessibility issue for authors to remediate.
