Description

Airplane emoji completely breaks text rendering - regression since Qt 6.2.4

Sample code:

import QtQuick

Window {
    width: 300
    height: 200
    visible: true

    Text {
        anchors.centerIn: parent
        width: 200
        wrapMode: Text.WordWrap
        text: '✈️Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. '
    }
}

Qt 6.2.4:

Qt 6.3.2:
