macOS

Description

When running this example on Windows or Linux everything works as expected.

How to reproduce:

Click on the button
Red window should open, console should output qml: activate changed true
Click inside the "main" window, console should output qml: activate changed false

On macOS nothing is output which means the signal onActiveChanged is never triggered.

import QtQuick
import QtQuick.Controls

Window {
    id: root
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Button {
        anchors.centerIn: parent
        text: "click"
        onClicked: {
            window.show()
            window.requestActivate()
        }
    }

    Window {
        id: window
        width: 320
        height: 240
        visible: false
        flags: Qt.Popup | Qt.NoDropShadowWindowHint
        modality: Qt.NonModal
        transientParent: root.Window.window
        color: "red"

        onActiveChanged: {
            console.log("activate changed", window.active)
        }
    }
}

This is the output on macOS from qt.qpa.window logging category:
