Wind Charge's fall damage is not canceled by the slime block

Summary:
I simulated a trampoline in the game, using Wind Charge to launch myself upwards and slime blocks on the ground to stop my fall, however, it didn't work as I expected.
Observed Results:
Launching myself from a point Y above the slime block, using Wind Charge, when you land on the block to reduce the damage from your fall, your avatar will bounce off the block, however, you will still take all the fall damage, several times in a row
Expected Results:
The slime block should completely cancel fall damage after using wind charge
Obs:
I used regeneration 100 in the game, so I wouldn't die while jumping
