IE Quirks: List item disappears when editor does not have focus

[James Cunningham]

Steps to reproduce the defect:

1. Open the Ajax sample in IE Quirks mode.

2. Paste the following code into the source view.

<table border="1" cellpadding="1" cellspacing="1" style="width: 500px;">
	<tbody>
		<tr>
			<td>
				&nbsp;</td>
			<td>
				&nbsp;</td>
		</tr>
		<tr>
			<td>
				&nbsp;</td>
			<td>
				&nbsp;</td>
		</tr>
		<tr>
			<td>
				&nbsp;</td>
			<td>
				&nbsp;</td>
		</tr>
	</tbody>
</table>
<ul>
	<li>
		sdaufhuashdf</li>
	<li>
		khsadfkuajsfdi</li>
</ul>

3. Switch back to WYSIWYG mode & click into the editor to give the editor focus.

See that both list items are visible.

4. Click away from the editor to make it lose focus.

See that only one list item is visible.

Note: Once the editor regains focus (even by hovering over a toolbar button), the 2 list items are visible again.

Confirmed for IE7/8 Quirks Issue happens for me only when I switch from source to WYSIWYG.
