Title:
  Binding loops in implicitWidth with OTA 10 landing

Status in Canonical System Image:
  In Progress
Status in ubuntu-ui-toolkit package in Ubuntu:
  In Progress
Status in ubuntu-ui-toolkit package in Ubuntu RTM:
  Fix Released

Bug description:
  The simple code

  import QtQuick 2.4
  import Ubuntu.Components 1.3

  AbstractButton {
      implicitWidth: childrenRect.width
      implicitHeight: childrenRect.height
      Label {
          id: titleLabel
          text: "HOLA CARACOLA"
      }
  }

  is giving

  file:///home/tsdgeos_work/test/1.qml:4:1: QML AbstractButton: Binding loop detected for property "implicitWidth"
  file:///home/tsdgeos_work/test/1.qml:4:1: QML AbstractButton: Binding loop detected for property "implicitWidth"

  file:///home/tsdgeos_work/test/1.qml:4:1: QML AbstractButton: Binding loop detected for property "implicitWidth"

  file:///home/tsdgeos_work/test/1.qml:4:1: QML AbstractButton: Binding loop detected for property "implicitWidth"
  file:///home/tsdgeos_work/test/1.qml:4:1: QML AbstractButton: Binding loop detected for property "implicitHeight"

  with the OTA 10 landing as of today.

  This works fine without that landing and i think it's valid code that
  should not be giving out warnings like this.
