popupType "Popup.Window" does not respect modal property

Clicks behave inconsistently between Popup.Item and Popup.Window. Specifically, when using Popup.Item, the modal property prevents clicks from "going through" to the underlying item. However, when using Popup.Window, clicks bypass the modal behavior and interact with the underlying mouse area, contrary to expected behavior.

Expected Behavior:

When the modal property is enabled, interacting with the popup should require two clicks:

The first click to close the popup.
A second, separate click to interact with the underlying item.

I've attached a video that showcases the problem.

Actual Behavior:

With the modal property enabled, the first click both closes the popup and interacts with the underlying item in a single action, bypassing the expected separation of events.
 

import QtQuick
import QtQuick.Controls.Material

ApplicationWindow {
    id: root

    width: 640
    height: 480
    visible: true

    color: "#fff0f1"

    Menu {
        id: someMenu

        // popupType: Popup.Item       // <- toggle here
        popupType: Popup.Window     // <- toggle here

        modal: true
        dim: false

        Action {
            text: qsTr("Press me")
        }
    }

    MouseArea {
        anchors.fill: root.contentItem

        onPressed: {
            root.color = "#7b4e7f"
        }

        onReleased: {
            root.color = "#fff0f1"
        }
    }

    Button {
        text: `Click to open Menu`
        anchors.centerIn: root.contentItem

        onClicked: {
            someMenu.open()
        }
    }

}
