Description

I can reproduce this issue with a standard Combo box with no effects added, but adding the easing function, as below, makes it far easier to reproduce.

Steps to reproduce:
1. Create a Flex web application and paste in the following code (see below).
2. Open and close the combo box (or start it opening and then click elsewhere) Note: do not wait for the combo to fully open before getting it to close.

Actual Results:
More often than not you can 'confuse' the combobox so that when you open it and try to use it, it automatically closes (actually the dropdown just disappears from view)

Expected Results:
The user should be able to open & close the combobox repeatedly (even if one transition has not fully completed) and it should still function as expected.

Workaround (if any):
None.

Code to paste in to Application file:

<!-- This error can be reproduced using a normal ComboBox with no easing applied
but applying easing makes it even easier to reproduce. -->
