Description

Steps to reproduce:

1. Create a combobox
<mx:Combobox id="my_combobox" dataProvider="

{my_arraycollection}

"/>

2. Programmatically change a combobox width in actionscript :
my_combobox.width = 500;

AND/OR change combobox dropdownwidth
my_combobox.dropdownWidth = 500;

Actual Results:
Combobox is correctly resized BUT dropdown width is not changed unless you selectedItem is changed by user.

Expected Results:
dropdown width should either adjust to new combobox size or be equal to the new dropdownWidth.

Workaround (if any):
If width changed on creationComplete, it works, the bug happens when width or dropdownwidth is progammatically changed later during runtime.
It seems that this bug is NOT present in SDK 3.4, but it IS present in SDK 3.5

Though it is ok in SDK 4.0
