TinyMCE issue with table wrapped with shortcode

[wpweaver]

TinyMCE will generate unbalanced <p> tags when a table is included as the content of a wrapping style shortcode. In this example, assume a shortcode called [div] ... [/div] that simply brackets the content with a <div> ... </div>.

This is an example as it would be in the editor's Text view (and it works if you switch back and forth to Visual.):

---

There will be a table following.

[div]
<table>
<tbody>
<tr>
<td>Simple table</td>
</tr>
</tbody>
</table>
[/div]

Next line is here.

---

The HTML output generated is this:

<p>There will be a table following.</p>
<div></p>
<table>
<tbody>
<tr>
<td>Simple table</td>
</tr>
</tbody>
</table>
<p></div>
<p>Next line is here.</p>

---

The shortcode is very simple - just a demo. It returns simply:

return '<div>' . do_shortcode($text) . '</div>';

Doesn't seem to matter with or without the do_shortcode() call.

---

So note the excess </p> after the added starting <div>, and the extra <p> before the </div> from the shortcode. Seems to happen only with a wrapping style shortcode, and I think only with tables.
