    Description

      The QML ComboBox popup (dropdown) menu keeps the original ComboBox size, even after applying a scale transformation. The ComboBox visual width and height changes, but the popup menu size keep the same.
      This is causing the user to think the application is broken.

      The sample application source code is attached. Screenshots were taken from the running application.
