Enchanted armor pieces worn by entities lose their enchantment glint when looked at from certain angles

Sometimes the enchanted glint on helmets worn by armor stands disappear if the player stares at nothing, which is air. The glint comes back if the player stares at a block. Only happens if facing west.

Due to the bug introduced in 20w10a which is MC-173747, you are unable to see this as the glint has disappeared.
