      6 <!-- Testcase for bug 879963 regression.
      7 
      8     This test is designed to hit the case where we were adding the same
      9     proxy font entry to a family multiple times during user font set updates.
     10 
     11     Note that if a platform doesn't have any of the local() fonts listed,
     12     the testcase will "pass" harmlessly as a no-op. -->
