--- Comment #1 from Benjamin Poulain <benjamin at webkit.org> ---
This one is very tricky.

There are many valid use cases for calling preventDefault() on touch events. I suspect we would mostly break content if rules start ignore it.

A problem is that we do not provide a way for the page to only cancel certain native gestures. It is quite possible the long press is only cancelled as a by-product of another gesture handling.

I'll import this too to keep track of this particular problem, but IMHO extending the platform should have the priority.
