   • [Qt Widgets] Menu Example: https://doc.qt.io/qt-6/qtwidgets-mainwindows-menus-example.html
   • [Qt Quick] "Sharing context menus" full snippet: https://doc.qt.io/qt-6/qml-qtquick-controls-contextmenu.html#sharing-context-menus
2. (If mouse is available on the device) Right-click on the center of the example
3. Long-press on the center of the example

Outcomes

• (Step #2) A context menu appears (Expected)
• (Step #3, Windows) A context menu appears (Expected)
• (Step #3, most other platforms) No context menu appears (Not Expected)
