video demo of issue

When using voiceover and navigating a table with the role of grid using arrow key navigation the table column header (th) value is not announced when focusing on each table data cell (td). This occurs on both Chrome and Safari. Note the column header info is correctly announced when using VO + arrow keys.

This behavior can be reproduced by navigating the WAI ARIA APG Data Grid examples: https://www.w3.org/WAI/ARIA/apg/patterns/grid/examples/data-grids/

Steps to repro:
-go to the URL provided above.
-with VO on, navigate the table with arrow key navigation
-Notice the column headers are not announced for each <td>.
-Notice the column header info is correctly announced when using VO + arrow keys.
