Sound duplication with chest

Fall damage sound can be twice heard when we open and quickly close a chest after hitting the floor.

What I expected to happen was...: When falling and open a chest, we should hear :
1) "Crack" sound of falling damage
2) Chest opening sound
3) Chest closing sound

What actually happened was : With a good timing, we can hear :
1) "Crack" sound of falling damage
2) Chest opening sound
3) Second "Crack" sound of falling damage
4) Chest closing sound

Steps to Reproduce:
1. Build a tower (mini 3 blocks high), with a chest near of it (accessible after jumping)
2. Jump of the top of the tower, in order to have falling damage.
3. Just after hitting the floor, open the chest and quickly close it. You should hear a second falling damage sound when the chest close.
