      Description

      Since JavaFX 8, hiding a popup causes that the owner window is focused, when the popup gets hidden.
      It used to work well in JavaFX 2.2!

      This is troublesome, because it then "steals" the focus from another window, where the user might work in.

      The Notifications control from ControlsFX is affected by this bug as well.

      The following app starts the primary stage ("Main Stage"), and periodically opens and hides popups (primary stage is owner).

      Then, if you focus the other stage (title: "Focus me!!"), the primary stage will get focused again, when the popup is hidden, which disturbs the user in his work (e.g. when he's typing in a TextArea).

      A popup should not focus its owner stage, when hiding.
