Splash Potion of Saturation has no effect

Splashing yourself with a potion that has Saturation edited onto it through the CustomPotionEffects list tag renders you with no Saturation effect.

You can use the following command to generate such a potion to test with:

/give @p minecraft:splash_potion 1 0 {CustomPotionEffects:[{Id:23,Amplifier:0,Duration:1}],Potion:"minecraft:empty"}
