Scaling a DateChooser inside a Canvas causes RTE

Steps to reproduce:
1. Compile and run:

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">

<fx:Declarations>
<s:Parallel id="scale">
<s:Scale scaleXFrom="0" scaleXBy="1" scaleYFrom="0" scaleYBy="1" />
</s:Parallel>
</fx:Declarations>

<s:VGroup>
<s:Button label="run effect" click="scale.play([target])" />
<mx:Canvas>
<mx:DateChooser id="target" />
</mx:Canvas>
</s:VGroup>

</s:Application>

2. Click the first button
3.

Actual Results:

RTE:

Main Thread (Suspended: ArgumentError: Error #2004: One of the parameters is invalid.)
flash.display::Graphics/drawRoundRect [no source]
mx.controls::DateChooser/updateDisplayList
mx.core::UIComponent/validateDisplayList
mx.managers::LayoutManager/validateDisplayList
mx.managers::LayoutManager/doPhasedInstantiation
mx.managers::LayoutManager/doPhasedInstantiationCallback

Expected Results:

No RTE and the DateChooser scales

Workaround (if any):

Use a spark container instead of mx:Canvas
