回血问题

当时，我在下界，战斗中，发现，饱食度是满的，不能进食，而生命值不回复，当我使用跳跃消耗饱食度再吃东西后，血量成功回复，没添加任何数据包和模组。

At that time, I was in the Nether, during the battle, and found that the satiety was full, I couldn't eat, and the health did not recover, and when I used the jump to consume the satiety and then ate, the HP was successfully restored, without adding any packets and mods.
