Description

Found in 4.1.0.14151

Steps to reproduce:
1. Compile and run attached MXML file.
2. Click the top ComboBox control to open the drop down.
3. Click the top ComboBox control to close the drop down.
4. Click the bottom ComboBox control to open the drop down.
5. Click the bottom ComboBox control to close the drop down.

Actual Results:
Step 5 doesnt close the ComboBox.

Expected Results:
Step 5 should close the ComboBox control, that way it is consistent with the behavior in step 3.

Workaround (if any):
(a) Disable the ComboBox dropdown drop shadow by setting the dropShadowVisible to false and then set the ComboBox dropdownStyleName style, as seen in the following example:

@namespace s "library://ns.adobe.com/flex/spark";
@namespace mx "library://ns.adobe.com/flex/mx";

.foo

{ drop-shadow-visible: false; }

mx|ComboBox

{ dropdown-style-name: foo; }

(b) Select an item in the ComboBox or click outside the ComboBox to close the drop down.
