Accessing a ListView attached property from inside a ListView's delegate while a ListView attached property is used within the ListView but outside of the delegate, and the linter's configuration (.qmllint.ini) has AttachedPropertyReuse=warning, results in an attached-property-reuse warning from QML linter.

The following code triggers the warning:

    ListView {
        anchors.fill: parent
        model: 1
        orientation: ListView.Horizontal
        delegate: Rectangle {
            width: 200
            height: ListView.delayRemove ? 20 : 40
            color: ListView.isCurrentItem ? "red" : "blue"
        }
    }

The following code doesn't trigger the warning:

    ListView {
        anchors.fill: parent
        model: 1
        orientation: Qt.Horizontal
        delegate: Rectangle {
            width: 200
            height: ListView.delayRemove ? 20 : 40
            color: ListView.isCurrentItem ? "red" : "blue"
        }
    }

By setting orientation to use a Qt enumerator, the attached-property-reuse warning isn't triggered. The warning appears to come from the attached property being accessed from different scopes (in and outside the delegate).

I suspect this might be intended behavior, but if this were the case then I would recommend updating ListView's documentation to suggest using Qt namespace enumerators where applicable instead of ListView's to prevent the warning.
