Two Level Focus

I'm wondering how well the Conditional Feature "TWO_LEVEL_FOCUS" works,
and if it is allowed to be used on non-embedded platforms.
My main JavaFX project is basically a Windows/Linux application that
runs without focus and is controlled with a remote control (no mouse or
keyboard, although keyboard events are synthesized). This means I often
run into problems related to the Window not having focus (controls donot
show it, combobox drop downs close automatically, etc.)
While fixing yet another of these problems in custom controls / skins, I
ran into the Conditional Feature above, which quite accurately describes
what I'm doing (remote control only has left/right/up/down and an OK
button... and a back button) which qualifies as two level navigation I
think. So I tried turning this on on Windows using:
...which I dug up out of Jira. This changes ComoBox control atleast to
not respond to "up" and "down" keys when it has the focus, allowing me
to move away from it. However, if you do click on it with the mouse (by
selecting one of its items), focus is stuck there and cannot be moved
anymore with just the 5 buttons.
Anyway, this sounds like it is exactly what I need and may save me a lot
of work, any more information about it is appreciated!
