Touch event handling on new Kobo Reader for iOS Japanese

[rtmyers]

I am testing a scripted book on the new Kobo Reader for iOS, Japanese version. I find that touch events, even when I explicitly try to stop propagation with stopPropagation or preventDefault (which works fine on iBooks), nevertheless make their way to the top level, where they are re-interpreted as commands to flip to the previous page (if towards the left side of the screen) or right page (if towards the right side of the screen). Needless to say, this makes the book completely useless.

Does anyone have any experience with the touch event handling logic and its interaction with event handling logic in user scripts in the Kobo code base?
