testname format still prints failure output with --hide-summary=output

[Tadimsky]

I would like to use the testname format for our tests as we like being able to see each test that passed. However, when a test fails, it prints out all of the output of that test which in our case can be many megabytes of log output.

I've tried suppressing this with --hide-summary=output but it looks like it's not from the summary and is rather part of the testname output.

I'm running these tests in GitLab CI and so whenever there is a test failure GitLab is unable to capture all of the output and so we can't see what actually happened. I'm sending the standard-verbose output to a file so I can look there to see exactly what happened.

Is there some config that I'm missing that will let me do this? Or is this something that testname does not support?
