Here's a code snippet which illustrates the problem:

Rectangle {
    fill: bind LinearGradient {
        endX: 0
        stops: [
            Stop { offset: 0, color: Color.BLACK },
            Stop { offset: 1, color: Color.WHITE },
        ]
    }
}


When I format this, I end up with this:

Rectangle {
    fill: bind LinearGradient {
        endX:  0
        stops:  [
            Stop { offset:  0, color:  Color.BLACK },
            Stop { offset:  1, color:  Color.WHITE },
        ]
    }
}

There are now extra spaces before all the property values in this object -- before the 0's, 1's, Colors, and even before the sequence [.

I'm not sure what about this code fragment triggers this, because I haven't seen it in other similar objects in the files I've just tried formatting.
