When requesting focus to a javafx node which is inside a JFXPanel when the jfxpanel is not the focus owner of the Swing Focus Manager, the JFXPanel is not focused. This cause the javafx node to presented as is didn't receive the focus even when the node is marked as the focus owner in the scene.

Example:
1. Press the swing button
The text field is not presented as focused.
