            Bug ID: 210716
           Summary: pointermove event sometimes has incorrect pointerType
                    of 'mouse'
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: iPhone / iPad
                OS: iOS 13
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: UI Events
          Assignee: webkit-unassigned at lists.webkit.org

On my 2017 iPad Pro 9.7", when running inside a WKWebView, a 'pointermove' listener attached to 'window' will sometimes incorrectly have its 'pointerType' property set to 'mouse' (instead of 'touch') even when no (Bluetooth) mouse is connected. This is very problematic because we use this event and its 'pointerType' property to detect if an actual mouse is connected, which now won't work.
