             Summary: Unable to consistently scroll diagonally in iOS
                 Key: CB-13189
                 URL: https://issues.apache.org/jira/browse/CB-13189
             Project: Apache Cordova
          Issue Type: Bug
    Affects Versions: cordova-ios@4.4.0
         Environment: iOS 10.3.3
            Reporter: Jack Anderson
            Priority: Minor


When there is an intentional overflow on the x and y axis of an iOS wkwebview, it is extremely difficult to scroll diagonally.

If the user scrolls one pixel directly up, they cannot then scroll horizontally in the same motion. This goes vice-versa for an initial horizontal scroll.

The only way to actually enable a "free-pan" scrolling experience, is for the user to perform a very very precise initial diagonal motion.

I see reference to this behavior in the native iOS UIScrollView documentation: https://developer.apple.com/documentation/uikit/uiscrollview/1619390-directionallockenabled

I've had a difficult time tracking down much on this topic, and have not found much discussion.
