Saturation with an AreaEffectCloud

I don't seem to be able to use

{Effect:[{Id:23, [...] }]}

on an AreaEffectCloud - it simply gives no effects and everything else works perfectly.

Exact command I'm using:

/summon area_effect_cloud ~ ~ ~ {Particle:mobSpell,ReapplicationDelay:10,Radius:2.5f,RadiusPerTick:-0.0025f,RadiusOnUse:-0.05f,Duration:1000,DurationOnUse:0f,WaitTime:0,Effects:[{Id:23,Amplifier:2,Duration:600,ShowParticles:0b}],Potion:"minecraft:water"}

What I expected to happen:
Saturation effect applied to player

What actually happened was:
No effect was applied

Steps to Reproduce:
1. Put the command above in a command block
2. Activate the command block
3. Stand in cloud; no effect is applied
