Reproducer:

@Serializable
data class ByteHolder(val a: Byte)

@Test
fun test() {
    val element = Json.decodeFromString<JsonElement>("""{"a": 1111}""")
    println(Json.decodeFromJsonElement<ByteHolder>(element))
}

Expected behaviour: SerializationException is thrown
Actual behaviour: ByteHolder(a=87) is printed
