Enemies can't push a player character when in critical strike stance

Steps to reproduce:

• get an axe and equip it, you can use this console command to get one:

player->additem "steel battle axe" 1

• Attack some NPCs.

• Hold the attack button so your character is in critical strike stance but don't hit anyone.

• Let the NPCs hit your character.

They won't be able to push the player character (or at least that's what happened to my character so far), this gives a bit of an advantage to the player in combat.
