STR: Expected: Users should be able to smoothly scroll through the Add Contacts page in the Contacts. Actual: Users during September 2012 usability test had difficulty scrolling through the Add Contacts page without accidentally launching the keyboard. Build: 2012-09-18 10:21:32

cc'ing Casey. Casey, Mary is beginning to generate bugs based on their user testing. Just FYI.

Noming for review. drag motion seems broken in some sense.

I think the problem here is that if the user touchstarts (or mousedowns) a touchable element X, moves a distance that's far enough that the user doesn't think it's a tap, but the touchend/mouseup happens on the same element X, then our code considers that a tap rather than a drag. preventDefault()ing the touchend/mouseup when the distance from touchstart/mousedown exceeds a "tap" threshold should fix this.

This same problem happens in the settings app, too, btw. It can be difficult to pan around with the panning being halted by a misinterpreted tap event.

Relatively minor usability issue, not blocking per triage.

Not blocking, but incredibly -expletive- annoying. Should fix for v1.

Is close corollary of bug 766066, which is blocking+. So we should either dupe this or mark it blocking.
