AX: Voiceover does not read table first cell content when table located inside element with role "dialog" when page is traversed using VO + Right Arrow key combination

Steps to Reproduce:
1). Please use the following code snippet:
<div role="dialog">
  <p>Text content</p>
  <table>
    <caption>Table caption</caption>
    <tbody>
      <tr>
        <td>Table body cell 1</td>
        <td>Table body cell 2</td>
      </tr>
      <tr>
        <td>Table body cell 3</td>
        <td>Table body cell 4</td>
      </tr>
    </tbody>
  </table>
</div>

2). Perform navigation through the snippet using VO + Right Arrow hotkey combination, navigate to table and then to the first table cell.

Actual Results: First table cell information and content are not announced, Voiceover only announces that you are currently on a table cell and key combinations that can be used for further navigation.

Expected Results: First table cell information and content are announced, then Voiceover announces that you are currently on a table cell and key combinations that can be used for further navigation.

Build Date & Hardware: Safari 16.0 (17614.1.25.9.10, 17614) on MacOS Monterey 12.6

Additional Information:
1) It is also reproduced if the table is constructed using non-native table elements and appropriate table roles. Please see the following code snippet.
<div role="dialog">
  <p>Text content</p>
  <div role="table" aria-label="Table caption">
    <div role="rowgroup">
      <div role="row">
        <span role="cell">Table body cell 1</span>
        <span role="cell">Table body cell 2</span>
      </div>
      <div role="row">
        <span role="cell">Table body cell 3</span>
        <span role="cell">Table body cell 4</span>
      </div>
    </div>
  </div>
</div>

2)Navigating to next table cell using VO + Arrow Right keys and then back to first cell using VO + Left Arrow keys will result in announce of first cell content, however navigating outside table and entering it again via VO + Arrow Right will not announce cell content again.

3) If <table> element is not placed inside element with role "dialog" everything is been read as expected.

Thanks for filing, this does not reproduce for me on Safari 16.4. Are you still seeing this on the latest release of Safari Technology Preview?
