Hi there, we have got some custom hook that has to run for each test and we are using pre-test for that. There is a problem though when I run the tests in isolation with `./bin/kaocha --fail-fast --watch --focus 'com.company.my-ns/test' I basically always detect that the testable in input is never a leaf, and I cannot run my pre-test code...is there another way to focus on a test leaf?
