Are web_sys methods auto generated?

Summary

I'm working with mouse events for my project, and I came across a very interesting method name for MouseEvents. The method is called

init_mouse_event_with_can_bubble_arg_and_cancelable_arg_and_view_arg_and_detail_arg_and_screen_x_arg_and_screen_y_arg_and_client_x_arg_and_client_y_arg_and_ctrl_key_arg_and_alt_key_arg_and_shift_key_arg_and_meta_key_arg_and_button_arg_and_related_target_arg

This seems a bit long. Do we generate method names? Is there a way to override them? It just seems really off to have method name this long.
