Description Wenson Hsieh 2017-06-26 17:53:08 PDT
Upon exiting a WKContentView, the dropSession is not cleared out. If the drag session re-enters the WKWebView, a *different* UIDropSession is sent to the drop delegate, causing us to bail in -dropInteraction:canHandleSession: and not handle the drag.

To fix this, we need to clear out dropSession when the drag session exits the view.
