Can't make object float on FLIP simulation

Hey all. I've got a FLIP simulation of icing being poured on a cupcake, and I want to drop an object on top of it, but no matter what I do, the object ignores the particles and falls through—it should float on top of them. I've tried changing the densities, particle separation, feedback scale... nothing seems to work. What am I missing?

Thanks!

Here's a basic setup demonstrating the flip feedback scale in operation. As you can see the collider treats the flip icing as a wall. If you're trying to embed the geometry partially into the icing, take a look at a few of the donut tutorials with sprinkle icing. It's just a boolean VDB after the sim
