This looks like a webkit bug, but it might be something we can work around. We should regress this with the new 2.1 build of Tizen.
We tested it on the tizen 2.1 load and issue still exsits.
I found that it's related to the Scroller in this example. On Tizen we aren't setting a strategyKind for scrollers so it gets the default scrolling on the platform. Didn't dig deeper than this into why but if I force any other strategyKind then it fixes the issue.
After a quick chat with Gray to confirm, I'm going to do some rough testing to determine what strategyKind works best on the platform & then (assuming one is a good fit) I'll update Scroller.js to force a default strategyKind for Tizen.
good catch... I'd say the default touch scroller probably is best, as the other ones are either a little broken (Transition) or Android specific.
