if i start breaking a door from the bottom and then move my camera up to the top of the door and vice versa the breaking animation resets

So i was playing on my survival smp and then i wanted to replace my birch door with an oak door so i started breaking the birch door, i know this sounds like something no human will ever do but i changed my camera position from the bottom to the up and then my breaking animation resets, and vice versa.
