is this necessary as well?

Done.

   color: rgba(0, 0, 0, .5);

why is this here?  specificity issues?  intentional differences from the rest of
chrome?  in general it'd be best to just have everybody agree.

I suppose, links were made gray to match the rest of the Print Preview UI in the
disabled state.

Thank you for asking, I realized that links cannot be disabled the same way as
buttons. Fixed that too.
