LNG-214 Compiler fails on nested ability function call

On such a code snippet:

data Struct:
    int: i8

ability Simple:
    st: Struct
    arrow(x: i8) -> bool

ability Complex:
    simple: Simple
    field: string

func foo{Complex}() -> bool:
    <- Complex.simple.arrow(
        Complex.simple.st.int
    )

func main() -> bool:

    closure = (x: i8) -> bool:
        <- x > 0

    MyComplex = Complex(
        simple = Simple(
            st = Struct(int = 0),
            arrow = closure
        ),
        field = "complex"
    )

    <- foo{MyComplex}()

Compiler errors internally:

ApplyPropertiesRawInliner.scala [ERROR] Inlining, cannot find field Complex.simple in ability var{Complex: scope Complex{field: string, simple: scope Simple{arrow: (x: i8) :: ∅ -> bool :: ∅, st: Struct{int: i8}}}}..
