Menu: Use StyleItem as a property
The count
property of the QQC2.Menu component shows the number of visual children. StyleItem is a visual element, so it will affect this property. This behavior can lead to an error when, for example, the user does not want to show an empty menu when accessing the "count" property.
To check the behavior you can look here if in the file examples/TableViewTutorial/contents/ui/TableViewPage.qml
you remove the action property on line 29
