It has no intrinsic ratio.

An SVG has an intrinsic width or height if the 'width' or 'height'
attributes are specified on it.  It has an intrinsic ratio if the
'viewBox' attribute is specified on it (in which case the ratio is
determined from the ratio of the width/height of the box so
specified), or implicitly if it has an intrinsic width and height.
(Having any two of width, height, and ratio implies the third
automatically.)

So, the SVG in this test has an intrinsic height (due to the 'height'
attribute), but no intrinsic width or intrinsic aspect ratio.
