here an extreme case ``` intersect Acts::PerigeeSurface: Center position (x, y, z) = (2998.3168793, 474.3935881, -3004.7428436) from pos -0.007314 0.046232 -0.015186 with direction 0.701984 0.111057 -0.703481 navDir backward StandardAborters: setStepSize...

the overall effect with the `ConstrainedStep`. the direction is flipping back and forth I am starting to wonder if `ConstrainedStep` should be allowed to change the direction https://github.com/acts-project/acts/blob/main/Core/include/Acts/Propagator/ConstrainedStep.hpp#L90. if so...
