Inconsistent behaviour between qmlsc and JIT compiler when setting a property to "undefined"

// TestClass.h
class TestClass : public QObject
{
    Q_OBJECT
    QML_ELEMENT
    Q_PROPERTY(qreal value READ value WRITE setValue RESET resetValue NOTIFY valueChanged FINAL)

    // ...
};

// Main.qml
import QtQuick
import QtQuick.Controls.Basic
import ResetIssue

ApplicationWindow {
    width: 640
    height: 480
    visible: true

    TestClass { id: testClass }

    Column {
        Button {
            text: "Set"
            onClicked: testClass.value = 999
        }
        Button {
            text: "Call Reset Function"
            onClicked: testClass.resetValue()
        }
        Button {
            text: "Assign undefined value"
            onClicked: testClass.value = undefined
            // JIT: Calls reset function
            // AOT: Calls setter function with NaN
        }
        Label {
            text: "Value: " + testClass.value
        }
    }
}
