Mixing splash and non-splash potions in cauldron produces all splash potions

hello, im LordOfCheaters, a mobile player of Minecraft Bedrock Edition,

i noticed a bug with potions and cauldrons, for example, pick an potion of slow_falling (not splash), click on the cauldron and it fill it, normal but if we fill it with 2 drinkable potions, and we finish with a throwable, when we un-fill it with 3 glass bottle, we get 3 throwable, normally we have to get 1 splash and 2 drinkable, so it's a way to have splash potions without using 3 gunpowders, thanks for read this.        -LordOfCheaters
