In the following code, I have contrived a situation where the height of a Rectangle is Infinite before becoming a valid value.

import QtQuick
import QtQuick.Window

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Rectangle {
        property real divisor: 0
        width: parent.width
        height: parent.height / divisor
        color: "green"

        Timer {
            running: true
            interval: 1000
            onTriggered: parent.divisor = 1
        }
    }
}

While the height is Infinite, the Rectangle does not render, which is fine as the height is not valid. However once the height becomes a valid value, the Rectangle still fails to render.

This situation can (and did) happen in a real and valid scenario where items were scaled by a factor that involved division by a constant, and the chance order in which elements were initialised by the QML engine resulted in the binding being setup and evaluated before the constant received its value.

Can this be 'corrected' so that QML items can tolerate temporarily invalid dimensions (e.g. Infinite, NaN, negative x, y, width, height)?
