Full Page Editor - Copying a paragraph of text from a table cell, then pasting it into a new empty table cell removes the <p> tags. For example:
This is the original table cell with the original text:
<td>
<p><strong>Shirt</strong><br />
Uniquely simplify cost effective processes after backward-compatible value. Appropriately reinvent customized information with impactful materials. Conveniently benchmark strategic catalysts for change through functionalized applications. Quickly mesh backward-compatible testing procedures vis-a-vis low-risk high-yield schemas.</p>

Here is what it looks like in a new empty table cell:
<td><strong>Shirt</strong><br />
Uniquely simplify cost effective processes after backward-compatible value. Appropriately reinvent customized information with impactful materials. Conveniently benchmark strategic catalysts for change through functionalized applications. Quickly mesh backward-compatible testing procedures vis-a-vis low-risk high-yield schemas.</td>
I am able to replicate this on your demo page.
