- Launch the attached test case, which has the following scene graph: Accordion->TitledPane->GridPane->Nodes
- Expand the first TitledPane, and click on "Add row", which fill the GridPane
- Click in the first TextField, and Tab : the focus move to the Hyperlink "1", this is fine
- Click again on Tab : the focus move to the 2nd TitledPane : Bug. It should move to the CheckBox

Reproducing the same scenario, moving from one node to the other in the TitledPane works fine !
But after the latest node, the focus move to the "Add Row" Button, instead of the 2nd TitledPane : Bug.
