To be more specific, the suggestion to remove mention of percentage
intrinsic widths was made in
<http://lists.w3.org/Archives/Public/www-style/2010Nov/0077.html>,
discussed at the following telcon
<http://lists.w3.org/Archives/Public/www-style/2010Nov/0249.html> and
decided at the following telcon
<http://lists.w3.org/Archives/Public/www-style/2010Nov/0264.html>.

The relevant section of SVG 1.1 Second Edition notes is
<http://dev.w3.org/SVG/profiles/1.1F2/master/coords.html#IntrinsicSizing>.
 It explains how percentage values in @width/@height do *not* provide
an intrinsic width or height for the image; they merely affect the
size of the <svg> element within the image after the image's size has
been negotiated.

Opera's (and I guess IE9's) behavior is correct here, but as far as
CSS is concerned, the bullet is always a 1em square in every example
you provided.  SVG just draws within that square in different ways.
