Watch out for quirks mode.  Go to strict mode, and the bullets will be on the same line.

<!doctype html>
<body>
 <ul style="list-style-position: inside">
   <li>
     <ul>
       <li>
         <div style="">aaa</div>
</body>

WebKit has a quirk for nested lists that prevents the bullets from being on the same line.  It's ancient code, so I'm not sure how sane it is.  Anyway, use strict mode.

Yeah, I would like painting to remain an implementation detail for CSS2.1, but I think the spec dictating that the marker is not clipped by overflow and that it doesn't scroll with overflow is indirectly implying paint order and stacking rules.  The fact that no engines respect this text concerns me as well.

Mostly, though, I just want a clarification on text-align, since WebKit is the only engine to ignore text-align on outside bullets.  However, if we decide outside bullets *should* respect text-align, then the other stuff (especially the overflow clipping and scrolling) comes into question as well.
