[REG 6.5.0-6.5.2][macOS] Emoji edit menu items are not visible in a specific case

Emoji edit menu items are not visible if Platform MenuBar creation is postponed via Loader.
Regression since Qt 6.5.2.

Sample code

import QtQuick
import Qt.labs.platform as Platform

Window {
    width: 640
    height: 480
    visible: true

    Loader {
        id: menuBarLoader
        active: false
        sourceComponent: Platform.MenuBar {
            Platform.Menu {
                title: 'Edit'
                Platform.MenuItem { text: "Search..." }
            }
        }
    }

    Timer {
        running: true
        interval: 500
        onTriggered: menuBarLoader.active = true
    }
}

Steps to reproduce:
1. Build and run sample code
2. Observe macOS menu bar
3. Try to open system emoji panel (via "control+cmd+space" shortcut)

Actual results: missing emoji edit items in the menu bar, emoji panel can't be opened via the shortcut
Expected results: emoji edit items are present in the menu bar, emoji panel can be opened via the shortcut
