Invulnerability timer resets when attacking with higher damage than previous one while invulnerable

When you inflict damage to a mob and inflict another with higher damage while the mob is invulnerable, the mob's invulnerability timer will reset and take knockback. This is not a case in Java Edition, where doing the same will only inflict only the difference between the previous and new damage amounts to be dealt, without resetting invulnerability timer.
