Here is my first test on the html5 combobox.

Unfortunately lots of problems. Tested on iPad
1, It makes cubefaces seems visible.
2. Very bad panning. The pano just jumps around.
3. After second load it crashes.
Here is the page without it.

BTW Combobox in flash is worthless on Android. However normal combobox in html is perfect for loading panos.
Same behavior as on iPad/iPhone with a large popup
