Area: JavaFx application
Synopsis: There are two editable combobox on the javafx application and run it. Then you open up a new application such as notepad or others as you like. Next, you get back to the javaFx application and click one of the combobox on which you get focus, and go to not the javafx application you open up. At last you get back to the javaFx application and click another editable combobox you did not click before. Once you click on, the focus on two combobox will constantly be looping, non-stop unless you terminate the java.exe by Window Task Manager.

By my testing, the bug is checked out and reproduced very easily because even it is javafx application or Code: AnchorPane on JavaFx Scene Builder in where a lot of editable comboboxes are using, it is happening.
