            Bug ID: 197082
           Summary: AX:
           Product: WebKit
           Version: Safari 12
          Hardware: Macintosh
                OS: macOS 10.14
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility

In an effort to provide a table with a "caption" by use of ARIA, I ran into unexpected behavior.

Using aria-labelledby on a table element to point to paragraph, the table semantics were removed.  No role is exposed in Safari's accessibility node inspector.  VoiceOver + Safari announced the table as a group.

Chrome exposes the table as a layoutTable in its inspector.

I then tried aria-describedby, and the title attribute.  With both of these attributes placed on the table element no role is exposed, VoiceOver doesn't announce it as a group.


Reduced test case:

Testing with Firefox and IE11, the above mentioned issues do not occur.  

Using JAWS with Firefox and IE11, the tables all announce as expected.

Expected Behavior

If a table is provided an aria-labelledby, it should be given an accessible name (like caption does).
If a table is provided an aria-describedby or title attribute, it should expose a description.

In neither situation should the table be converted to a layoutTable.
