When using TAB or SHIFT-TAB keys to cycle through the HelloTitledPane sample, focus is attemped on the "Not Collapsible" Titled Pane header, but since it is non-focusable, there is no focus on anything at that point. Pressing TAB or SHIFT-TAB once more brings focus to the next item normally. It seems that the non-focusable "Not Collapsible" Titled Pane header should be skipped while changing focus.

To reproduce:
1. Bring up HelloTitledPane sample (java -cp Hello.jar hello.HelloTitledPane)
2. Press TAB until focus is on "Button" in the Titled Pane "Not Animated" (This pane should already be expanded on start up).
3. Press TAB once more. The focus is not to be seen anywhere.
4. Press TAB again, the focus is now on the "Button" in the "Not Collapsible" Titled Pane.
5. Using SHIFT-TAB going the other direction has the same result.
