Disappearing bottles/potions when drinking and switching at the same time

In Survivalmode: When drinking a potion of any kind and switching to another potion in your hotbar shortly before the drinking-animation ends the potion you switched to will dissappear from your inventory, relogging will not let the potion reappear.

In Creativemode:  When drinking a potion of any kind and switching to another potion (of another kind)  in your hotbar shortly before the drinking-animation ends the potion you switched to will become the potion you drank, relogging will not let the potion reappear.

This bug is recreatable and does appear everytime when switching to the other potion is timed right.
