Qt.SizeAllCursor is not correct in QtQuick

When setting the cursorShape of MouseArea to Qt.SizeAllCursor, the observed cursor differs from the the documentation.

Instead of the anticipated Qt.SizeAllCursor, it seems to resemble the Qt.ClosedHandCursor.

The comprehensive project is included in the attachment. This discrepancy is evident on Ubuntu/X11 and Ubuntu/Wayland, but functions as expected on the Windows platform.

import QtQuick
import QtQuick.Controls
Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")    
    MouseArea {
        anchors.fill: parent
        cursorShape: Qt.SizeAllCursor
    }
}
 

The screenshot of the program is as follows.
