Error with parameterless extension method overload resolution

[nicolasstucki]

minimized code

object Test {
  given (a: Int) {
    def foo(i: Int): Unit = ()
    def foo: Unit = ()
  }
  val x: Int = 5
  x.foo(4)
  x.foo
}

fails with

11 |  x.foo
   |  ^^^^^
   |  value foo is not a member of Int - did you mean x.+?.
   |  An extension method was tried, but could not be fully constructed:
   |  
   |      Test.given_foo_of_Int.foo(Test.x)

expectation

It should compile and it should generate the same code as

object Test {
  given (a: Int) {
    def foo(i: Int): Unit = ()
    def foo(): Unit = ()
  }
  val x: Int = 5
  x.foo(4)
  x.foo()
}

which does compile.

This also occurs when there are given parameters

object Test {
  given (a: Int) {
    def foo(i: Int)(given Long): Unit = ()
    def foo(given Long): Unit = ()
  }
  given Long = 9
  val x: Int = 5
  x.foo(4)
  x.foo
}

10 |  x.foo
   |  ^^^^^
   |  value foo is not a member of Int - did you mean x.+?.
   |  An extension method was tried, but could not be fully constructed:
   |  
   |      Test.given_foo_of_Int.foo(Test.x)
