So maybe we should explicitly add this case in css3-lists?

In addition, we have another problem that if there is a counter-style
called 'inside' or 'outside' and it is directly assigned to
'list-style-type', what serialized value should be returned for
'list-style'? If we returned 'outside outside none', than it breaks our
rules. Considering this, maybe we should completely exclude these two
keywords from possible counter style names.
