Bug 176077 – [iOS] REGRESSION (r218144) -[WKContentView targetForAction:withSender:] returns the content view for actions implemented only by the WKWebView, causing a crash

• Component: WebKit2
• Status: RESOLVED FIXED

<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.

Hm...I wonder if this functionality should be in a testing category on WKWebView in TestWKWebView.h instead -- I imagine it could be useful for other tests as well, not just this test (at a brief glance, WKContentViewEditingActions.mm also needs the same functionality).

Nit - I would prefer auto here.
