2D View does not process enums correctly

Code

import QtQuick

Text {
    id: root
    width: 100
    renderType: Text.NativeRendering
    text: renderType === Text.NativeRendering ? "Native" : "Not Native"
}

Steps to reproduce
Check the 2D View, Live Preview, and Properties pane after each step below:

1. Put the code above into a *.ui.qml file
2. Replace === with !==

Expected outcomes (Live Preview/Propererties)
Step #1 shows "Native", Step #2 shows "Not Native"

Actual outcomes (2D View)
We get the opposite of the expected outcomes
