Accessibility tags for repeated table header

I'm seeing a tagging issue when creating a PDF from a Word document that has a table with "heading rows repeat" selected, when the table goes onto multiple pages. The resulting PDF tags include a <tr> / <th> node for the heading each time the heading appears on the top of a page. My understanding is that this tag structure does not meet the PDF accessibility standards, yet that is how the Adobe product generates a PDF.

This issue was simiarly discussed here: https://community.adobe.com/t5/acrobat-discussions/tagging-repeating-table-header/m-p/12094073

Manually addressing this, through something like changing it to an artifact, is not particularly reasonable due to the workflow in my office (which involves a high volume of documents created on a short timeline). I have not found a straightforward programmatic remediation approach either, as the general Acrobat API seems quite limited in traversing document content and handling tagging. 

This is using Word for Microsoft 365 on a Windows 10 PC. The PDF is being created from the Acrobat Add-In within Word (i.e., the Acrobat ribbon > Create PDF). Some document properties:

Application: Acrobate PDF Maker 25 for Word

PDF Producer: Adobe PDF Library 25.1.213

PDF Version: 1.6 (Acrobat 7.x)

Any help is welcome!
