Why is a different extension function called depending on whether one is expect or not?

common module:

sealed class Test {
	object A : Test()
}

If I don't use `expect`:

fun Test.print() {
	when (this) {
		is Test.A -> print() // calls method below
	}
}

fun Test.A.print() { // gets called
	println("A")
}

If I use `expect`:

fun Test.print() {
	when (this) {
		is Test.A -> print() // recursive call
	}
}

expect fun Test.A.print() // not called

That seems to be a problem in ambiguity resolution. Could you report it ln kotl.in/issue and link it back here?
