I'm not sure about this. If the writing modes spec is more stable than the
ruby spec, I guess it is probably better to only have it in the ruby spec.
But I have no idea how this could be specified in a different spec than the
one which defines the property. Anyway, I'm not familiar with editorial
things like this.

The computed values, same as what the current spec does on ruby-position:
inter-character. I don't think it makes sense to have different value for
computed one and effective one here.
