Description

Steps to reproduce:
1. Compile the attached file (Test1.mxml)
2. Run the result
3. Click the button to run state1 > state2 transition
4. Click the button again to run state2 > state1 transition

Actual Results:
Top "white" rectangle flickers to its state2 size at the end of the state2 > state1 transition
This doesn't happen all the time, but I'd say it happens well over 50% of the time

Expected Results:
No flicker, smooth resize during both state1 > state2, and state2 > state1 transition

Workaround (if any):
Increase background rectangle opacity to 100%.
I tried to simplify the file as much as I could, it appears to happen when an object with < 100% opacity is transitioning, and another object is transitioning on top of it. It's not limited to resizing transitions. Test2.mxml involves a position transition.
