This signal is emitted when a select element in @web_view needs to display a
dropdown menu. This signal can be used to show a custom menu, using @menu to get
the details of all items that should be displayed. The area of the element in the
#WebKitWebView is given as @rectangle parameter, it can be used to position the
menu.
To handle this signal asynchronously you should keep a ref of the @menu.
