-[WKWebView _ignoresNonWheelMouseEvents] and -[WKWebView _setIgnoresNonWheelMouseEvents:] are part of a class extension, but have implementations in WKWebView (WKPrivate), which override the synthesized accessors (since there are no overrides in the class @implementation). Fortunately the linker emits warnings about this: ld: warning: instance method '_setIgnoresNonWheelMouseEvents:' in category from WebKit2.build/Debug/WebKit.build/Objects-normal/x86_64/WKWebView.o overrides method from class in WebKit2.build/Debug/WebKit.build/Objects-normal/x86_64/WKWebView.o ld: warning: instance method '_ignoresNonWheelMouseEvents' in category from WebKit2.build/Debug/WebKit.build/Objects-normal/x86_64/WKWebView.o overrides method from class in WebKit2.build/Debug/WebKit.build/Objects-normal/x86_64/WKWebView.o
