            Bug ID: 194995
           Summary: [iOS] Adjust initial scale zooming heuristics when
                    changing view scale
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: wenson_hsieh at apple.com

Currently, we only zoom to the new initial scale iff we're exactly at initial scale before changing the view scale. This was done so that if a user zoomed in really far and then increased the view scale, we wouldn't end up zooming out as a result.

Per conversation with Tim and Yongjun, we should consider changing the heuristics here, such that:
• If the view scale is increasing and the new initial scale is greater than the current scale, zoom to initial scale.
• Likewise, if the view scale is decreasing and the new initial scale is less than the current scale, zoom to initial scale.
