Multiple selectors setting relative font-weight names to an element result in a cumulative result
According to http://dev.w3.org/csswg/css-fonts/#font-weight-prop, the computed
weight of 'lighter' and 'bolder' are based on the inherited 'font-weight', so set
that inherited weight before calculating 'lighter' and 'bolder'.
