rowgroups and their labelling are not perceptible

[JAWS-test]

Summary

Example:

1. Go to https://codepen.io/jaws-test/pen/BagVVpN
2. Read table content with arrow key down
3. Read table content with CTRL+SHIFT+arrow keys

Expected result

The two examples from WHATWG show the use of rowgroups and their labelling with th scope=rowgroup. I expect:

• to hear the start and end of the groups
• to hear the labelling of the groups when I enter the group (whether from above or below)

See: https://html.spec.whatwg.org/multipage/tables.html#header-and-data-cell-semantics

If the principal cell is anchored in a row group, then add all header cells that are row group headers and are anchored in the same row group with an x-coordinate less than or equal to principalx+principalwidth-1 and a y-coordinate less than or equal to principaly+principalheight-1 to header list.

If the principal cell is anchored in a column group, then add all header cells that are column group headers and are anchored in the same column group with an x-coordinate less than or equal to principalx+principalwidth-1 and a y-coordinate less than or equal to principaly+principalheight-1 to header list.

Actual result

Neither the groups nor their labelling is output by JAWS

It does not work with NVDA either.

If the groups are explicitly labelled (e.g. via aria-label), then I can hear the groups and their labels when reading with the arrow keys, but not when navigating in tables. There is already a ticket for this problem, which has unfortunately been closed
