In 2.2.40 Shift_TAB when focus is on the first control inside a TitledPane doesn't go to the TitledPane's expand/collapse control, but skips to the focusable control ahead of the TitledPane. This works in JavaFX 8.

If both 2.2.40 and JavaFX 8 (Lombard):
When focus should move to an expanded TitledPane with focusable controls after a Shift-TAB, rather than the last focusable control in the TitledPane receiving focus, The focus jumps across all of the controls in the titledPane to the expand/collapse widget of the TitledPane. This is non-intuitive for users, as they see the contents of the TitledPane as the controls preceding the currently focused control. This also means that focus traversal in the forward direction is not the reverse of focus traversal in the backward direction. I.e. TAB followed by Shift+TAB doens't get you back to where you were.
