Sets a custom title for the #GtkHeaderBar.
The title should help a user identify the current view. This supersedes any title set by gtk.header_bar.HeaderBar.setTitle or gtk.header_bar.HeaderBar.setSubtitle. To achieve the same style as the builtin title and subtitle, use the “title” and “subtitle” style classes.
You should set the custom title to null, for the header title label to be visible again.
