IntelliJ Kotest doesn't show tests failed with exception

Question

Code

I have the following three tests:

import io.kotest.core.spec.style.BehaviorSpec
import io.kotest.matchers.shouldBe

class Example {
    fun blah(number: Int): Int {
        if (number == 1) {
            throw IllegalArgumentException()
        } else {
            return number
        }
    }
}

class ExampleTest : BehaviorSpec({
    Given("example") {
        val example = Example()
        When("calling blah(0)") {
            val result = example.blah(0)
            Then("it returns 0") {
                result shouldBe 0
            }
        }
        When("calling blah(1)") {
            val result = example.blah(1)
            Then("it returns 1") {
                result shouldBe 1
            }
        }
        When("calling blah(2)") {
            val result = example.blah(2)
            Then("it returns 2") {
                result shouldBe 2
            }
        }
    }

})

Problem

The middle test throws an exception which is not expected. I would expect to see 3 tests run, 1 of which failed, but what IntelliJ and Kotest plugin show me is that 2 out of 2 tests passed. I can see in the Test Results side panel that something is not right, but it doesn't have any useful information.

If I navigate to the index.html with tests results, I can see everything correctly. I would like to see the same data in IntelliJ.

Screenshots

IntelliJ output: Note that:

• on the left the test for number 1 is missing
• at the top it says "Tests passed: 2 of 2"
• on the left there are yellow crosses up to "Given", but all tests in "Given" are green
