bazel: test_verbose_timeout_warnings giving strange results

I ran the test below with --runs_per_test=3 --test_verbose_timeout_warnings.

The test is sized medium, which is documented to expect to fall within 30s-300s. Yet you can see below that it ran in 61.8 seconds, and I’m still getting a warning.

Also, the warning always states that the test ran in 0.0s. This is what it shows for every test, no matter how long it actually took.
