In principal, maybe they do, but typically those sizes are not exposed to
the browser and are not used in layout.

SVG images often don't have an intrinsic size. What's the intrinsic size of
this image?
<svg xmlns="http://www.w3.org/2000/svg">
  <linearGradient id="g" x1="0" y1="0" x2="1" y2="0">
    <stop stop-color="red" offset="0"/><stop stop-color="lime" offset="1"/>
  </linearGradient>
  <rect x="0%" y="0%" width="100%" height="100%" fill="url(#g)"/>
</svg>

healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
