Description

Steps to reproduce:
1. Start the attached application in Profiler
2. Click "Add component"
3. Click "Remove component"
4. Run Garbage Collector in Flash Profiler a few times

Actual Results:
The added component (ExampleView) as well as the TextInput within the ExampleView hasn't been garbage collected.

Expected Results:
The ExampleView and TextInput should have been garbage collected since there shouldn't be any references.

If you execute steps 2 and 3 multiple times all except one instance of ExampleView and TextInput get garbage collected.

I reproduced the bug with a Group component instead of TitleWindow as ExampleView as well as a Button instead of a TextInput. It looks like the child components stop the GC from collecting the containers.
