Vector: Don't supress focus outline on watch star

This is an old remnant that was intended to remove outline from
images inside anchor links. However the watch star is no longer
implemented this way and this is doing nothing. Except when
the element is focussed (using keyboard tab index), then this
rule is overriding the default :focus and causing the user to
potentially get confused since it is no longer clear where the
focus has gone to.
