[D1, module, type conflict] Which bug is this?

[%u]

Disregard that, here is the real bug. I removed the circular struct definition.

The code below results in:
i.d(7): Error: b.B at b.d(5) conflicts with c.B at c.d(3)

But if the selective imports are changed to non-selective public imports( bug[314]
) the error is gone.

--
module main;
import c;

void main(){}
--
module c;
import i;
import b : B;
//public import b;

class C : I{
  this(){}
  B fb(){
    B b;
    return b;
  }
}
--
module i;

import b;
import c;

interface I{
  B fb();
}
--
module b;
import a : A;
//public import a;

struct B{
  A a;
}
