Fix the pseudo-link styles

Make the target inherit the global `font` (necessary for `button`) and
receive the correct cursor style.

Remove the inheritance of `text-decoration` as the placeholder anchor is
_inside_ the target, so this has no effect.

Keep the background of the target transparent when it is
hovered/focused, etc.
Remove `text-decoration` from default linkComplex

Ensure that the default linkComplex does not have any text decoration,
even when the global link style includes text decoration on standard
anchors. This insulates the utility from variance in the global styles
of documents it might be used within.
