object defined in Selectable has undefined type

[bishabosha]

Minimized code

def foo = new reflect.Selectable { object Foo }

Output

-- Error: objectinselectable.scala:1:4 ----------------------------
1 |def foo = new reflect.Selectable { object Foo }
  |^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  |{...}.this.Foo$ is not defined in inferred type {z1 => reflect.Selectable{Foo: z1.Foo$}}

Expectation

[bishabosha]

this also happens for general values of classes defined within the anonymous class:

def foo = new reflect.Selectable { class Foo; val f: Foo = Foo() }

[bishabosha]

for reference, in Scala 2 the following happens:

@ new {
    class Foo {
      class Inner {
        def foo = 23 
      }
    }
    val Inner = {
      val foo = new Foo
      new foo.Inner
    }
  } 
res0: {type Foo <: AnyRef{type Inner <: AnyRef{def foo: Int}};val Inner: this.Foo#Inner} = ammonite.$sess.cmd2$$anon$1@43826ec
