PDF Export - Emoticons Are not Rendered When Placed inside Table Cells

We just experienced another bug of the PDF export when exporting pages that contains tables where emoticons are inside table cells.

Steps to reproduce

1. Create a page like:

   <p>The table below compares something, e.g. (<ac:emoticon ac:name="green-star" />), &quot;partially&quot; (<ac:emoticon ac:name="yellow-star" />), to &quot;limited&quot; (<ac:emoticon ac:name="blue-star" />) and &quot;no&quot; (<ac:emoticon ac:name="red-star" />) provision.</p>
   <p> </p>
   <table>
   <tbody>
   <tr>
   <td> </td>
   <td><strong>Column A</strong></td>
   <td><strong>Column B</strong></td></tr>
   <tr>
   <td colspan="3"><span style="color: rgb(0,128,0);"><strong>Functional Properties</strong></span></td></tr>
   <tr>
   <td>Enter some text</td>
   <td>
   <div align="center">
   <p><ac:emoticon ac:name="green-star" /></p></div></td>
   <td>
   <div align="center">
   <p><ac:emoticon ac:name="green-star" /></p>
   <p>some text</p></div></td></tr>
   <tr>
   <td colspan="3"><strong>Heading 2</strong></td></tr>
   <tr>
   <td>  Point A</td>
   <td>
   <div align="center"><ac:emoticon ac:name="green-star" /></div></td>
   <td>
   <div align="center"><ac:emoticon ac:name="red-star" /></div></td></tr>
   <tr>
   <td> Point B</td>
   <td>
   <div align="center"><ac:emoticon ac:name="green-star" /></div></td>
   <td>
   <div align="center"><ac:emoticon ac:name="blue-star" /></div></td></tr></tbody></table>
   

2. Observe that the emoticons are rendered on the page
3. Export the page to PDF
4. Observe that the emoticons are rendered outside the table, but those inside the table are not rendered

Any clue why this issue exists?
