How to override some properties of TableView.rowDelegate while keeping others default

I'm using a rowDelegate to implement variable row heights as follows. However, it doesn't use the default background colors for selected/alternate rows. How can I preserve all defaults that I'm not trying to override?

TableView {
        id: messagesTable
        TableViewColumn {
            role: "severity"
            title: ""
            width: 20
            delegate: Image {
                anchors.centerIn: parent
                fillMode: Image.Pad
                source: iconSources[styleData.value.toLowerCase()]
            }
        }
        TableViewColumn {
            role: "message"
            title: "Message"
            width: 300
        }
        TableViewColumn {
            role: "source"
            title: "File"
            width: 150
        }
        TableViewColumn {
            role: "startLine"
            title: "Line"
            width: 40
        }
        TableViewColumn {
            role: "startColumn"
            title: "Column"
            width: 50
        }
        rowDelegate: Rectangle {
            width: childrenRect.width
            height: (messagesModel.get(styleData.row).lineCount || 1) * 20
        }
        model: messagesModel
    }

You can't.

The general rule of styling with Qt Quick Controls is: once you override a delegate, you start from scratch. If the styles provided a DefaultTableViewRowDelegate type, for example, you could construct an instance of that and then it would work, but since the default delegates are written inline, you have no way of accessing them.
