Unable to Add Whitespace After Hyperlinks

[miqrogroove]

This bug seems to have developed somewhere after version 3.1.

To reproduce this bug:

1. Start a new post or page.
2. Click the HTML tab.
3. Paste this snippet:

<ul>
	<li><a href="http://www.google.com/">Parent item</a>SPACEME
		<ul>
			<li>Child item</li>
		</ul>
	</li>
</ul>

4. Click the Visual tab and note how the hyperlink runs up against the word "SPACEME".
5. Click the HTML tab.
6. Add a space before "SPACEME".
7. Click the Visual tab.
8. Like magic, the space has vanished! :(

Curiously, I am unable to reproduce this behavior if I add the space on the Visual tab rather than the HTML tab. Very buggy!

Tested 3.4.2 with all plugins disabled, using Chrome 21, IE 8, Opera 12, Firefox 13, and found the same problem in all browsers.

Confirmed in trunk.

The problem seems to exist only in a list when a submenu inside of a <li> has been defined.

Thank you both for testing.
