`DescribeSpec` test with `InstancePerLeaf` isolation mode appears running forever

[lwasyl]

This is what I see after running the test class:

The tests appear to have completed successfully, and the infinite spinner seems to be just visual bug.

Sample test:

Repro code

```kotlin package com.example import io.kotest.core.spec.IsolationMode import io.kotest.core.spec.style.DescribeSpec class TestTest : DescribeSpec() { init { describe("test") { println("Starting") describe("First describe") { println("first describe") it("should do something") { println("assertion") } it("should do something else") { println("second assertion") } } describe("Second describe") { println("second describe") it("should do something") { println("assertion") } it("should do something else") { println("second assertion") } } } } override fun isolationMode(): IsolationMode? = IsolationMode.InstancePerLeaf } ```

debug output ``` invokeBeforeProject ~~~ Kotest Configuration ~~~ -> Parallelism: 1 thread(s) -> Default test timeout: 600000ms -> Default test order: Sequential -> Default isolation mode:
