Non breaking spaces added by DW
When editing in live view window (but also present in design view), adding new list items to a UL will insert a non breaking space in the last item. It will remain in that until you add another by clicking to the right of the last one and using enter to insert another. That causes it to move to the new LI item. If you click outside the edit box or use escape to stop editing, the non breaking space is left in the LI.
It also does this when splitting a paragraph using enter.
<li>even more testing</li>
<li>once more </li>
The non breaking spaces can only be removed manually in the code window, since DW appears to protect those above deleting content near them when using the DEL or backspace key.
On a related note, DW seems to ignore my preference for disallowing multiple spaces when pressing the spacebar, instead it happily inserts more non breaking spaces in place of simple spaces.
Another bug, or by design?
