Actually, IE quirks mode is more or less just "render like IE6", so you 
can't read much into whether IE does something in quirks mode past the 
fact that IE6 did it.

That then involves defining what the box _is_.  This sounds like it 
could get pretty complicated, especially if list-style-position:inside 
blocks are nested.

I'm having trouble telling what webkit is actually doing based on this 

   <ul style="list-style-position: inside">
           <div style="">aaa</div>

It seems like the outer bullet is placed on a line by itself but the 
inner is not, right?

> The only differences between the two are that the outside marker doesn't affect the placement of objects on the line, and the outside marker gets a paint translation applied to shove it outside.

The outside bit there seems like an implementation detail... In Gecko, 
the same effect is achieved through totally different means.
