Input widgets/controls ignore ImhFormattedNumbersOnly/ImhDigitsOnly

import QtQuick 2.15
import QtQuick.Controls 2.15
import QtQuick.Window 2.15

Window {
    width: 640
    height: 480
    visible: true
    color: "lightgrey"

    TextField { inputMethodHints: Qt.ImhFormattedNumbersOnly }
}

Run this code on a machine in touchscreen mode.

• Expected outcome: A numpad keyboard should appear.
• Actual outcome: A QWERTY keyboard appears.

 
Notes

• Android produces a numpad keyboard by default, but Windows 10 does not
• Widgets also behave the same (tested with QLineEdit with lineEdit.setInputMethodHints(Qt::ImhFormattedNumbersOnly) )
• Same results when using Qt.ImhDigitsOnly
