    <!-- WHEN YOU FIX A LINT WARNING, ADD IT TO THIS LIST.

         We want all lint warnings to be fatal errors.
         This is the list of checks that we've explicitly

         we switch to the `warningsAsErrors` lint option
         (bug 1253737) rather than listing everything explicitly. -->
