Description:
When the player has the slow falling effect, the advancement "Who needs rockets?" is granted if the player falls 8 blocks or more below the y-position they launched from using a wind charge, even if the height they reached using the wind charge was not 8 blocks above the y-position they launched from.
How to reproduce:
1. Apply slow falling effect to yourself
2. Using a wind charge, launch yourself to any height less than 8 blocks above the height you launched from
3. With slow falling still in effect, fall to a height any more than 7 blocks below the height you launched from, and the "Who needs rockets?" advancement will be granted.
Expected results:
The player would not be granted the "Who needs rockets?" advancement, as they did not launch 8 or more blocks above their original position.
Actual results:
The player is granted the "Who needs rockets?" advancement.
