Behavior on height in a QML file is ignored

If a component has a Behavior on height defined this Behavior is not executed:

// SomeComponent.qml
Item  {
  Behavior on height { ... }
}

Behavior on height defined at instantiation of the component works fine:

// main.qml
SomeComponent { Behavior on height { ... } }

See the attached example for a demonstration: the Behavior on opacity in main.qml works while the Behavior on height in OtherComponent is ignored (the change in height is not animated).

I have bisected qtdeclarative and think the bug was introduced by 81867dfbf QML: Introduce write accessors to QQmlAccessors .

Edit:
It works fine if the behavior in OtherComponent is "Behavior on opacity" - so it depends on both the property (height) and the place where the behavior is defined (in OtherComponent.qml).

Edit 2:
It also works fine if height is changed directly. The bug is triggered if height is changed by a binding like: height: collapsed ? 200 : 400
