Contrary to MC-257082, which appears to have been resolved inadvertently. It seems Mojang deemed initiating sprint while riding an entity unnecessary, thus they eliminated the ability, except for camels. However, sprinting while mounted on entities isn't futile as it enables knockback attacks against mobs. This implies that whenever you aim for a knockback attack with increased force while mounted, you must dismount and then remount the entity while sprinting. Remember that initiating a knockback attack by attacking an entity interrupts sprinting, necessitating you to start sprinting again for subsequent knockback attacks.

Steps to test the bug

1. Summon a boat
2. Summon a mob
3. Mount the boat
4. Attempt to execute a knockback attack on the mob by sprinting

Observation: It's not possible to initiate sprinting for a knockback attack.
Expectation: You ought to be capable of initiating sprinting for a knockback attack.
