This does not have to be blocked by bug 23496.

This bug is tricky to fix, because to do it right we'll need to fix how
toggleCSSStyle works.  Right now the ApplyStyleCommand (which gets generated by
the toggle callback) does not really know that it's supposed to remove just one
CSS value from a CSSValueList.  Instead, it knows how to set a css property to
a specific value.  We may need to make a whole new Command to handle
text-decoration (or toggles in general).
