If we accept the conclusion of that thread, that merely says that we
shouldn't be making any tests that depend on the activation or lack of
activation on non-focusable elements at all.  The 3rd link in this
test goes against that, as it depends on all forms of activation to
not activate the <span>.

(I don't accept your conclusion in that thread, though - by common
agreement between all browsers, clicking is an activation behavior,
and all elements respond to clicks by becoming :active.  This isn't a
matter of bugwards compat or not, it's just a matter of your personal
opinion differing from the interoperable opinion of all browsers.  We
should indeed be testing and requiring this behavior.  If you believe
we need a disclaimer about the it, so be it, but that shouldn't
prevent us from testing interoperable behavior.)

Clicking on the text of the link means clicking on the <span>.  By
virtue of the <a> being the <span>'s container, it's also clicked
on/activated.  There is no grounds for assuming that only the <a>
should be :active and not the <span>, though.
