When pinching happens in a PinchHandler, an overlapping TapHandler sometimes also triggers

import QtQuick
import QtQuick.Window
Window {
    width: 500; height: 500; visible: true
    Rectangle {
        anchors.fill: parent
        color: "#dddddd"
        PinchHandler {
            property real initScale: 0.0 // to save baseline scale factor of the tappableRect when pinch starts
            target: null // because we want to handle activeScale changes ourselves
            grabPermissions: PointerHandler.CanTakeOverFromAnything // when pinch is happening, tap should NOT happen
            onActiveChanged: {
                if (active) {
                    initScale = tappableRect.scale;
                }
            }
            onActiveScaleChanged: {
                if (active) {
                    tappableRect.scale = initScale * activeScale;
                }
            }
        }
        Rectangle {
            id: tappableRect
            property bool toggled: false
            width: 100; height: 100; x: 100; y: 100
            color: toggled ? "green" : "red"
            TapHandler {
                // in the hopes that pinching abandons a potential tap
                grabPermissions: PointerHandler.ApprovesTakeOverByAnything | PointerHandler.ApprovesCancellation
                onTapped: {
                    tappableRect.toggled = !tappableRect.toggled;
                }
            }
        }
