If your example was
   <del>one <span><span>two</span></span></del>
then of course the line-through should cross "one" and "two".

Your specific example runs into this clause, however:

   # [Text decoration] is not, however, further propagated to floating and
   # absolutely positioned descendants, nor to the contents of 'inline-table'
   # and 'inline-block' descendants.
