It sets both to `numSteps`, however, in the real case scenario `currentStep` will be `numSteps` and `previousStep` will be `numSteps - 1` at the end of the FTU. Since the navigation progress bar logic now depends on the difference between the two, it will not work with `setStateStep(numSteps)`.

Of course I can change `setStateStep` to properly updated the two, what do you think?
