[James Cunningham]

Steps to reproduce the defect:

1. Open the Ajax sample in IE8.

2. paste the following code into the source view.

<ul dir="rtl">
	<li>
		list item 1</li>
	<li>
		list item 2</li>
	<li>
		list item 3</li>
	<li>
		list item 4</li>
	<li>
		list item 5</li>
	<li>
		list item 6</li>
	<li>
		list item 7</li>
	<li>
		list item 8</li>
	<li>
		list item 9</li>
	<li>
		list item 10</li>
	<li>
		list item 11</li>
	<li>
		list item 12</li>
	<li>
		list item 13</li>
	<li>
		list item 14</li>
	<li>
		list item 15</li>
</ul>
<p dir="rtl">
	paragraph 1</p>

3. Switch back to WYSIWYG mode.

4. Right click on the bulleted list to display the context menu.

5. Click on the bulleted list properties option in the context menu.

Expected: The Bulleted List Properties dialog is displayed.

Actual: The Bulleted List Properties dialog is not displayed.

Shares the same reason with #7472 where resize handler eclipsed the context menu.

Just noted that #7472 is is closed, let's mark this one as a DUP also.
