Interesting.

Other way around - this is a list-related feature (highlighting the
contents of the element when you click the bullet) being shoehorned
into a CSS feature (the "display:list-item" value) that isn't
restricted to lists.

This is identical to automatically putting table-sorting functionality
on anything that specified display:table, which would be obviously
silly.  The Firefox behavior should be limited to the <li> element,
which is semantically a list item (if it's kept at all).
