title: WebKitWebProcess makes new dock icons
body: <p>When running a WebKitGTK+ application on macOS, every instance of the WebKitWebProcess makes a new dock icon. Is there a way to disable/fix this behavior?</p>
  <p>Suggestions to use lsuielement (<a href="https://developer.apple.com/documentation/bundleresources/information_property_list/lsuielement" rel="nofollow noreferrer">https://developer.apple.com/documentation/bundleresources/information_property_list/lsuielement</a>) have not worked. It seems that WebKit itself and/or GTK is forcing each WebView widget to have a new application icon in the dock.</p>
