the enderdragon has a bug with the its breath that can crash your game or kill you

I was in my hardcore survival world fighting the dragon for the 12th time and i decided to start collecting its dragon breath and when it landed on the bedrock portal at 0, 0 it did the normal thing where it would breath its breath and i saw that the more dragon breath i collected the more would appear so i turned a auto clicker on and collected some of the dragons breath and it almost killed me and got me down to 1 fps and covered 50+ block circle around the dragon with dragon breath.
