>                 Key: FLEX-35125
>                 URL: https://issues.apache.org/jira/browse/FLEX-35125
>             Project: Apache Flex
>          Issue Type: Bug
>          Components: Spark: DropDownList, Spark: PopUpAnchor
>            Reporter: Mihai Chira
>            Assignee: Mihai Chira
>             Fix For: Apache Flex 4.16.0
>         Attachments: Reproduce.mxml
> *Steps to reproduce*:
> # Run the attached code
> # Open the first DropDownList
> # Open the second DropDownList
> *Actual behaviour*: the first DropDownList is not closed.
> *Expected behaviour*: the first DropDownList is closed.
> *Notes*:
> * this is how it usually works when the components are not inside a PopUpAnchor
> * it relates to the DropDownLists not receiving the {{FocusEvent.FOCUS_OUT}} event when
the other one is clicked, as ought to; {{DropDownListBase.focusOutHandler()}} is never called,
even when the user clicks outside the application, whereas for DropDownLists on the stage
the function is called for both these scenarios.
> * If we wrap the {{HGroup}} inside a {{TitleWindow}}, all works as expected. That's because
{{TitleWindow}} implements {{IFocusManagerContainer}} and, as described in {{PopUpManager}},
"If the class implements {{IFocusManagerContainer}}, the window will have its  own {{FocusManager}}
so that, if the user uses the TAB key to navigate between controls, only the controls in the
window will be accessed."
> * There is code in to keep the DropDownList open if the click was made on another DropDownList.
This was implemented as a fix for FLEX-34088.
