There are no red steps on the bisect, because the failure happened on the builder. Bisect requested a build, and then it determined that the build had failed. This being on the reference range, it bailed as expected.
Rather than making a step artificially red, I'll make sure the message says something like: "Failed because building one of the revisions in the reference range failed" and I will also try to provide a link to the failed revision
