Removing Items from unordered list (WinXP/IE8)

[tom]

I've got a problem with unordered / numbered lists with IE8 on WindowsXP.

Create an unordered list with some items. Now try to get one item to the upper line with the "delete"-key. This will not work. If you try the "backspace"-key on the line that should be added to the item above you got an inconsistent list, because the </li>-Tag of the upper line will not disappear.

This error is not in Firefox3 (WinXP) and IE8 (Windows7)

This is also the case in ​http://ckeditor.com/demo/
