<https://trac.webkit.org/r218144> made -[WKContentView canPerformAction:withSender:] return YES for actions implemented by the WKWebView, but didn’t take care to override -targetForAction:withSender: to return the WKWebView as well. Without an override, the base implementation returns the WKContentView itself, which then gets sent an unrecognized selector.
