# the URL extension works even before the Django has been set up.
#
# Because if we define the component before `django.setup()`, then we store it in
# event queue, and will register it when `AppConfig.ready()` is finally called.
#
# This test relies on the "url" extension calling `add_extension_urls()` from within
# the `on_component_class_created()` hook.
