Richtmyer Meshkov instability in MHD

The Richtmyer Meshkov instability in Hydrodynamics:- 1) When shock wave interacts with the contact discontinuity, it accumulates the vorticity on the CD 2) This causes the density discontinuity to curl up, and form series of vortices

In application of the longitudinal magnetic field with conducting fluid as the working medium,

1) The RM instability is suppressed 2) Series of new shocks is formed and it carries away the vorticity

My question is , what exactly happens in Magneto-Hydrodynamic system? Why the RM instability is supressed? How can one get the physical intuition of what is happening at the interface?
