This test has been failing frequently in the CI. I think it has to do with the initial values being stochastic and sometimes giving combinations that lead to a derivative underflow in
float32. I fixed the testvals and made sure it passes onfloat32locally.Confidence this will fix issues: 85%
Closes #4661
Edit: to be clear I managed to induce the failure locally by running in a loop and monitoring the random start values. Fixing the observed start values to those made the test fail systematically. I am just not sure this was the only thing that was causing the failures.
