Its possible to collect any amount of dragon breath bottles within a few seconds.
How to reproduce:
1. Enter the End dimension.
2. Wait for Ender Dragon to perch at the middle.
3. Hit Ender Dragon a few times until it fires Dragon Fireball.
4. Enable hitboxes.
5. Collect whole purple cloud of Dragon breath(screenshot 1).
6. Spam click at the one pixel of hitbox left(screenshot 2).
With autoclicker I managed to collect 9 stacks of bottles from one cloud(the pixel that was left).
