            Bug ID: 150604
           Summary: Implement viewport-width-based fast-click heuristic
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: iOS
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org

Remove the experimental scroll/zoom-based heuristics for fast-clicking and replace it with a heuristic based on viewport width and current zoom scale. If the viewport width is equal to the device width and the user has not zoomed yet (i.e. at initial scale) then fire fast clicks instead of double taps. In all other cases, perform the old behavior. To make this optimization useful for width = device-width websites with scalable viewports, we also make double-tap-to-zoom-out change the viewport scale to be the initial scale rather than the min scale.
