shouldBeEqualToComparingFields breaks with a typealias of a Java type about kotest

[Kantis]

Would you like to contribute a test and/or fix?

This test triggers the behaviour if you step through it with a debugger but the test doesn't actually fail. It's happily recursing into a Map and I can't reproduce what it didn't like about that before. But it doesn't match the documented behaviour either way.

import io.kotest.matchers.equality.FieldsEqualityCheckConfig
import io.kotest.matchers.equality.shouldBeEqualToComparingFields
import org.junit.jupiter.api.Test

typealias MyMap = Map<String, String>

class ReproTest {

  data class Widget(val things: MyMap, val ignoreMe: String)

  @Test
  fun test() {
    val widget = Widget(mapOf("a" to "b"), ignoreMe = "blah")
    widget.shouldBeEqualToComparingFields(
        Widget(mapOf("a" to "b"), ignoreMe = "foo"),
        FieldsEqualityCheckConfig(propertiesToExclude = listOf(Widget::ignoreMe)))
  }
}
