Note that this does not happen with an euler integrator.

> The BracketingNthOrderBrentSolver used by the EmbeddedRungeKuttaIntegrator fails, if
an event is detected twice with a NoBracketingException.
> The problem lies in line line 262 (version 3.1.1). Here the event detection
function f is applied to an arbitrary choosen value of time. If the event detector crosses
zero before this time, the solver throws the mentioned exception.
