Description

Steps to reproduce:
1. Run the TestProject2.mxml in the profiler mode
2. Click on Add test instance button
3. Click on the combobox to expand the menu
4. Click outside of the list whitout selecting an item
5. Click on the Remove test instance button
6. Run the GC in the profiler perspective

Actual Results:
TestInstance2 stuck in memory
Each time you repeat this sequence you keep all the combobox's parents and itself in memory.

Expected Results:
Combobox and it's parent should be garbage collected, like in sdk 3.4

Workaround (if any):
Extend the combobox and override the close method as follow:
override public function close(trigger:Event = null):void

{ super.close(trigger); PopUpManager.removePopUp(super.dropdown); }

In ComboBox.as, line 2067 not triggered when we click ouside of the dropdown.
