For any component in ToolBar: onMouseClicked handler no longer triggers after it was clicked in popup state when ToolBar's width is minimized

For any component in ToolBar: onMouseClicked handler no longer triggers after you click on the component in popup state(when ToolBar's width is minimized and arrows ">>" is shown).
Look at the picture toolbarFXissue.png. After pressing on button "Extended search" in this state onMouseClicked handler no longer works ( while onAction still works properly).

Try JavaFXApplication.java to reproduce issue.
