I'm a little unclear on what it means to allow pinch-zoom without allowing pan-x and pan-y. Most if not all UAs that support pinch-zooming also allow panning around while both fingers are down - would this be disallowed? Pinch-zooming inherently changes the scroll position, and may do so differently depending on what the focus point of the pinch gesture is. This aspect of pinch-zooming could be considered orthogonal to panning, if we define panning strictly as gestures while a single touch point is down. The way the spec is currently worded, it refers to "scrolling" which could be interpreted as something that implicitly happens during a pinch-zoom, in which case disallowing pan-x and pan-y implicitly disallows pinch-zoom. (I should probably just try Edge and see what happens, but regardless, it's something that should be explicitly stated if this makes into the spec). -- GitHub Notification of comment by staktrace Please view or discuss this issue at https://github.com/w3c/pointerevents/issues/29#issuecomment-227762548 using your GitHub account
