+        [Mac] Make Clipboard class no longer polymorphic by removing the last virtual functions
+        https://bugs.webkit.org/show_bug.cgi?id=116166
+
+        Reviewed by Anders Carlsson.
+
+        * WebCore.exp.in: Add ~Clipboard since it's no longer a virtual function, but to the
+        non-iOS section, since iOS is still using the legacy version of Clipboard.
+
+        * dom/Clipboard.h: Mark items non-virtual, too. It's not implemented on Mac yet.
