Consider the following example image

This fails with 

Back-end (JVM) Internal error: Failed to generate expression: KtNameReferenceExpression
File being compiled: (1,28) in Line_7.jupyter-kts
The root cause java.lang.UnsupportedOperationException was thrown at: org.jetbrains.kotlin.codegen.context.ConstructorContext.getOuterExpression(ConstructorContext.java:65)

This code is legit in a main

import kotlin.random.Random

fun main() {
    val rand = Random(10)
    rand.nextInt()

    data class Foo(val smthg: Int = rand.nextInt() )

    println(Foo())
}

Environment: Windows10 & Kotlin kernel v. 0.10.3.31, Kotlin v. 1.6.20-dev-3702
