Description mitz 2018-10-08 11:38:40 PDT 
When using a mouse with a scroll wheel or trackball (as opposed to a multitouch device), wheel events all have their phase (and momentum phase) set to NSEventPhaseNone. Even if the web view is pinned and set to not rubber-band, it never delivers such events to the delegate via -_webView:didNotHandleWheelEvent:.
