No, because there is nothing on the line that would increase the line
spacing. The 'line-height' property sets the effective height of inline
boxes. The height of each line box is determined by vertical-aligning
all the content on the line and then calculating the height required
to contain everything on the line. In this case, there is only some
18px text with a line-height of 27px.

See http://www.w3.org/TR/CSS21/visudet.html#line-height

There is another problem with that test, though: it's quite difficult
(if not impossible) to figure out whether the UA has passed or not.
