Readonly TextArea accepts return key events when using RichText format

[Dan Chapman ]

When using a readonly TextArea like the snippet below, it still accepts return key events when the text format is set to TextEdit.RichText, resulting in either text being broken on to new lines or empty lines being created .

TextArea {
     anchors {
        left: parent.left
        right: parent.right
    }
    readOnly: true
    textFormat: TextEdit.RichText
    text: "I can break this line up with the Return key when textFormat: TextEdit.RichText"
}
