For the following src/Example.kt

}
fun testEnum(p: SingleEnum) = when (p) {
SingleEnum.First -> 1
}
fun main() {
testEnum(SingleEnum.First)
}
execution of
kotlin-2.0.21/bin/kotlinc src -d classes
java -javaagent:jacoco-0.8.13-SNAPSHOT/lib/jacocoagent.jar -cp classes:kotlin-2.0.21/lib/kotlin-stdlib.jar ExampleKt
java -jar jacoco-0.8.13-SNAPSHOT/lib/jacococli.jar report jacoco.exec --classfiles classes --sourcefiles src --html report

Expected behaviour
All lines of when expression should be fully covered as single enum element was passed
