Warden roar sound and animation don't play when the player is facing away from it

Description:
When facing away from the Warden, the "Warden roar" sound and animation doesn't play.

Steps to Reproduce:
1. Load into a flat world in creative mode
2. Using a Warden Spawn Egg, spawn the Warden
3. Switch gamemode into survival
4. Face away from the Warden while jumping to aggravate it

Observed Result:
The Warden roar sound and animation will not play.

Expected Result:
Warden roar sound and animation should play when the player is facing away from it.

Notes:

• In the following attachment, I jump up and down causing the Warden to become angry. Before the Warden roars, I face away from the Warden in 1st person. This causes no roar sound or animation to play.

• The roar animation and sound will play if the player is in 3rd person with the Warden in view

• The roar animation and sound will not play if the player is in 1st person without the Warden in view
