The fix for this issue was needed outside the WebKit project, therefore this is being resolved as 'Moved'.

This should now be fixed in shipping software.

Comment:

Note that in the provided CodePen example, the empty <div></div> inside the group role div seems making the tree being mapped to a regular group instead of a table in Safari, which could be another WebKit issue. Please verify after removing the empty <div></div> first so that the tree can be mapped to a table correctly, and after the <rdar://problem/73907428> is submitted.

Change this two line:

<div role="group" aria-owns="group1-item1 group1-item2 group1-item3" aria-label="Jungle Animals"><div></div></div>

<div role="group" aria-owns="group2-item1 group2-item2" aria-label="Ocean Animals"><div></div></div>

To:

<div role="group" aria-owns="group1-item1 group1-item2 group1-item3" aria-label="Jungle Animals"></div>

<div role="group" aria-owns="group2-item1 group2-item2" aria-label="Ocean Animals"></div>

So that the tree example can be correctly mapped to a table instead of group in Safari.

Thank you for the suggestion Eric. The fix you suggested worked and we can consider this one fixed. (Technically a WONTFIX as there's no need for a fix.)

Actually, I spoke too soon. This remains an issue remains.
