When testing the sliderEntry demo in the ace-showcase app, some strange focus-mgmt issues are apparent:

1. Try tabbing into the horiz. slider entry, then using the arrow keys to increase/decrease the slider value. SingleSubmit occurs, focus stays on slider, all good. Now tab onto the "Submit" button at bottom of demo, then Shift-Tab back up to the horiz. slider, use arrows to change value. Single-submit occurs, and focus is moved back to the Submit button! This will keep happening unless you focus on the inputText field above the horiz. slider, then back to the slider, then it's fine again. Is there something about the focus in the slider that makes it 2nd class element vs. the inputText and Submit button? It seems like the bridge's focus-retention feature is somehow sticking on the submit button once it's been focussed, until another native widget like the inputText is focussed.

2. Use the mouse to click on the horiz. slider bar (not the arrow itself, the bar beside it), slider moves to new position and gets focus, now keyboard arrows will adjust slider position. All good. Then click on vertical slider bar (not arrow). Focus is not set on vertical slider after clicking on bar for some reason. Not good.

Happens the same way on Safari 5, Chrome, and FF 3.6 ( all I tested).
