Despite Wardens having an attack knockback of 1.5, they don't deal knockback to players blocking with a shield, unlike ravagers. This might or not be caused by how they disable the player's shield after every attack, or might be another case of MC-235198 (Which this report has been split from).

I believe this is a valid issue since MC-217567 is a similar case, and has already been triaged.

How to reproduce

1. Summon a warden, apply yourself a high resistance effect.
2. Try to block a melee attack with a shield.
3. Notice how the shield has been disabled but you haven't been knocked back.

Expected result

The player would have taken knockback from the attack, like how it happens with ravagers and hoglins/zoglins.

Observed result

The player doesn't receive any knockback from hits blocked by a shield, despite normal hits dealing considerable knockback.
