Riptide tridents don't reduce fall damage

This bug has been since 1.16.200 i think
So if you use riptide trident upwards in mid air while falling it reduces the fall speed but doesnt reduces the fall damage
Even if you safely land using the trident it still gives the fall damage of the initial height
how to reproduce
Take a riptide 3 trident and fall from a very high height.
When close to the ground trident up and try to safely land.
observed results
The fall damage doesn't reduce even the falling speed is
