Layer set as passthrough works like moveable layer

I'm working on trying to finish a skin, but I've come across curious behavior. I have a layer which I have labeled as "base passthrough" but I can still click and drag it as if it were "base moveable"
This is particularly frustrating because it's essentially disabling all the controls that are on top of it (volumelr, play, pause, etc.) - when I click on those buttons they don't function as I'd expect - rather, they act as moveable layers.
