UI Dialog - Modal Overlay is broken in rc6


Hello,
In trying out rc6 I've found that I cannot use the modal overlay. I
reduced the page I was working on to a minimal test case and then also
tried rc6 out on a previous minimal test case I already had up at
jsbin.com. Here is a link to the test case. I have commented out the
link to rc5 and added the rc6 link. You can just comment rc6 out and
try it with rc5 to confirm it functions. I haven't been able to use
any modal overlays so far in rc6 in any of the test cases I've put
together. I am stumped.
