Empty Lines not counted within styleInfo

[nil-ableton]

While debugging a styled element, I sometimes look at styleInfo to show the origin of the rule being matched. I noticed that the line numbers were sometimes off by a few lines, which is confusing. After reproducing I figured that the line counts were incorrect because they seem to ignore empty lines. Here is a repro case: linenumbers-in-styleinfo.css

WidgetA {
    border-width: 0
}

WidgetA .title {
    fontSize: 24
}

import QtQuick 2.3 as QQ
import QtQuick.Layouts 1.2 as QQLayouts

import Aqt.StyleSheets 1.0 as Styles

    id: root

    height: 600
    Styles.StyleEngine {
        id: styleEngine
        stylePath: "../css"
        styleName: "linenumbers-in-styleinfo.css"
    }
    QQ.Text {
        id: debugInfoText
        property var debugText

        readonly property point anchorPoint: {
            if (debugInfoText.debugText) { 
                var input = debugInfoText.debugText;
                return root.mapFromItem(
                    input.originItem, input.x, input.y

                    return debugInfoText.mapFromItem(input.originItem, 0);
                }

                    QQ.Binding {
                        when: mouseArea2.containsMouse
                        target: debugInfoText
                        property: 'debugText'
                        value: ({ 
                            text: containedTitle.Styles.StyleSet.styleInfo,
                            originItem: mouseArea2, 
                            x: mouseArea2.mouseX, 
                            y: mouseArea2.mouseY,
                        })
                    }
                }
            }
        }
    }
}

Notice how the .title rule is said to be coming from line 6 when it actually comes from line 31
