Finite Elements for Fluids P1+P1 P2+P1

Dear Comsol users,

Comsol sets P1+P1 elements as default for laminar flow described by Navier-Stokes equations. As far as I know, theoretically, these elements are not good for such equations. Instead, P2+P1, or P2IsoP1 should be used. But Comsol uses those for creeping (Stokes) flow.

Is the comsol's P1+P1 choice stabilized in some way such that it can be used for Navier-Stokes?

I appreciate any hint.
Thank you
