java.util.NoSuchElementException when deserializing twice from the same JsonElement

[qwwdfsad]

Steps to reproduce:

@Serializable
sealed class Foo {
    @Serializable
    data class Bar(val a: Int) : Foo()
}
@Test
fun testFoo() {
    val json = Json.toJson(Foo.Bar(1))
    println(Json.fromJson<Foo>(json))
    println(Json.fromJson<Foo>(json))
}
