Description

Strangest thing, cannot determine cause. As soon as the number of tests exceed 31, the coverage report goes blank.
### At 31 tests:

### At 32 or greater tests:

Zero errors are thrown, the tests run and pass, but coverage is missing. Also it does not matter where or when the >31st test is.

Research direction

Start by reproducing the issue with 31 tests and then with 32 or more, comparing the coverage output. Trace the coverage report generation to find why it becomes blank while tests still pass; done means coverage remains present after adding the extra test.
