Sorry, but this is not a matter of my personal opinion. The HTML4 spec
gives no support to the idea of <span> being activateable, while it
does so for links and form elements; and the HTML5 spec explicitly
excludes it from its list of activateable elements. Given both these
facts and the current text of the CSS spec, there is absolutely no
reason why the CSS test suite should expect <span> to be activateable.

You are absolutely correct, under the assumption that the <span>
is activateable. However, that assumption is not valid under the
HTML specs. If the <span> is not activateable, and it is not in
the ancestor chain of an activateable element, then per CSS2.1 it
cannot match :active.
