Description

Steps to reproduce:
Try to open, then close, and then interrupting the close animation, reopen a single AccordionContent.

Actual Results:
An RTE might occur:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

at spark.components::AccordionContent/enterFrameHandler()[/Users/mvujovic/Documents/FlexSources/trunk/frameworks/projects/spark/src/spark/components/AccordionContent.as:648]

Expected Results:
No RTE.

Workaround (if any):
None.

Notes:
This is not a regression. I saw it before Bear's selection refactor. I think the destruction policy is being applied twice on AccordionContent (timing issues).
