User-Agent:       Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9) Gecko/2008052912 Firefox/3.0
Build Identifier: Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9) Gecko/2008052912 Firefox/3.0

Assume we have the following DOM structure. This can be obtained from the steps given below.

<ul _moz_dirty=""><li>a<li></ul>
<br _moz_dirty="" type="_moz"/>
<br _moz_dirty="" type="_moz"/>
<ul _moz_dirty=""><li>b</li></ul>

Now typing text in the second blank line between the UL's causes it to appear in the previous blank line. If we have more than two lines, typing text in the last line sometimes causes it to appear in the previous line and sometimes in the previous two lines.

Reproducible: Always

Steps to Reproduce:
1. Type one, enter, two
2. Select all and convert it into a bulleted or numbered list.
3. Place the cursor at the end of the bulleted item one and press enter twice to break out of the list and create a new line.
4. Repeat step 3 again to create another new line.
5. After this step, the HTML looks like.

<ul _moz_dirty="">
<br _moz_dirty="" type="_moz"/>
<br _moz_dirty="" type="_moz"/>
<ul _moz_dirty="">

6. Place the cursor in the second new line and start typing.
Actual Results:  
The text appears in the previous line.

Expected Results:  
The text should appear the cursor position.

This didn't manifest when we removed type="_moz" from the BRs in firebug.
