On X11 paste from the pasteboard...
Created attachment 30175 [details] Paste from GDK_SELECTION_PRIMARY Handle middle button press for PLATFORM(X11) after going through the event handler. We can call paste() without any guards as the Editor::paste implementation will verify that we can properly paste...
Comment on attachment 30175 [details] Paste from GDK_SELECTION_PRIMARY I think you can do without the new private function, since you can access the private data of the view from PasteBoardHelperGtk.cpp (we also access the 'disposing' flag from FrameLoaderClientGtk.cpp in a similar way). But it's not really important, so r=me either way.
