[Touch-packages] [Bug 1630167] [NEW] When SlotsLayout uses a Column as mainSlot and view is resized horizontally an inifinite resize loop starts

[Treviño]

Public bug reported:

With a simple code such as

import QtQuick 2.4
import Ubuntu.Components 1.3
import QtQuick.Window 2.0

Window {
    SlotsLayout {
        id: slotsLayout
        onHeightChanged: print("SlotsLayout height",height)
        width: parent.width
        mainSlot: Column {
            onHeightChanged: print("COlumn height",height)
            onWidthChanged: console.log("Column width", width)

            Rectangle {
                id: rect
                width: parent.width
                onWidthChanged: console.log("RECT WIDTH", width)
                onHeightChanged: console.log("RECT HEIGHT!", height)
                height: 5
            }

        }
    }
}


Or something similar (http://archive.is/N0jnM), when resizing the view 
horizontally to only use few pixels, an infinite resizing loop starts and the 
view freezes.
