I just upgraded from 3.1.3 to 3.2.1, and the 'indent' icon on the TinyMCE toolbar is producing invalid markup on nested lists
So I will make a list:
1) type line
2) select UL icon
3) make a few more lines
4) select line of text and click on 'indent' icon
5) save
...after I save, WP will fix the invalid nested code (I have the setting enabled under reading).
The toolbar is producing this code:
<ul>
<li>parent list item 1</li>
<ul>
<li>child list item 1</li>
</ul>
<li>parent list item 2</li>
</ul>
...instead of:
<ul>
<li>parent list item 1
<ul>
<li>child list item 1</li>
</ul>
</li>
<li>parent list item 2</li>
</ul>
