[FLEX-24663] wrong size in custom itemRenderers

• Type: Bug

Description

Steps to reproduce:
1. Use a UIComponent as an itemRenderer of a List (make it an IListItemRenderer first).
2. trace() the unscaledWidth and unscaledHeight in the components's updateDisplayList() method.

Actual Results:
The component's updateDisplayList method will be executed twice. The first time the unscaledWidth und unscaledHeight are correct (the size of the row). The second time (and last time) both are 0.

Expected Results:
UnscaledWidth and unscaledHeight should (at least) be the same as the size of the list's row. Even when I explicitly set a measuredWidth and measuredHeight in the component, it does not work. In DataGrid I found the same bug, also in Flex 4.1. I tried to use Container as base class too - no difference. See the example project in the attachment.

Workaround (if any): Unfortunately not.
