Emitted before a context menu is displayed in the UI Process to
give the application a chance to customize the proposed menu,
build its own context menu or pass user data to the UI Process.
This signal is useful when the information available in the UI Process
is not enough to build or customize the context menu, for example, to
add menu entries depending on the #WebKitDOMNode at the coordinates of the
@hit_test_result. Otherwise, it's recommended to use #WebKitWebView::context-menu
signal instead.
