Re: clicking outside of widget seems to disable NativePreviewHandler ONKEYPRESS

I've figured out that what's causing the loss of keyboard events is my
call to SimplePanel.setWidget(), which happens as part of my app's
navigation, via an Activity implementation. I've boiled this down to a
simple example that's repeatable (for IE8, at least):

Java code <a href="http://pastebin.com/ykjvcNRh">here</a>.
UI Binder: <a href="http://pastebin.com/kEPck03X">here</a>.

My work-around hack is to skip the setWidget() call in my Activity's
start() method, if the containerWidget already contains it. This is a
bit ugly, since the actual SimplePanel is wrapped by a
ProtectedDisplay, which requires me to pass around a reference to my
original panel. But it works.
