Tutorial on incompressible RAS eq. and lid-driven cavity not working as expected

Running pisoFoam on the folder tutorials/incompressible/pisoFoam/RAS/cavity/ (with default input) is expected to run the simulation up to 10s achiving a Courant of ~0.2 max. However, after time=2.5 the Courant number jumps to 1 and the solution becomes meaningless.
