UIInputManager does not react to DPad

[eruvanos]

Reproduce

import arcade
import warnings
from pyglet.input import Controller
from arcade.experimental.controller_window import ControllerView, ControllerWindow
from arcade import Window, View, ControllerManager, InputManager

class MyControllerView(View):
    def __init__(self):
        super().__init__()

        self.ims = []
        self.cm = ControllerManager()
        self.cm.push_handlers(self)

        # bind to existing controllers
        for controller in self.cm.get_controllers():
            self.on_connect(controller)

        self.default_input = InputManager(allow_keyboard=True)
        self.default_input.new_action("left")
        self.default_input.new_action("right")
        self.default_input.new_action("up")
        self.default_input.new_action("down")
        self.default_input.add_action_input("left", arcade.ControllerButtons.DPAD_LEFT)
        self.default_input.add_action_input("right", arcade.ControllerButtons.DPAD_RIGHT)
        self.default_input.add_action_input("up", arcade.ControllerButtons.DPAD_UP)
        self.default_input.add_action_input("down", arcade.ControllerButtons.DPAD_DOWN)

        self.default_input.new_action("a")
        self.default_input.new_action("b")
        self.default_input.new_action("x")
        self.default_input.new_action("y")
        self.default_input.add_action_input("a", arcade.ControllerButtons.BOTTOM_FACE)
        self.default_input.add_action_input("b", arcade.ControllerButtons.RIGHT_FACE)
        self.default_input.add_action_input("x", arcade.ControllerButtons.LEFT_FACE)
        self.default_input.add_action_input("y", arcade.ControllerButtons.TOP_FACE)

    def on_action(self, action, state):
        print(f"action: {action}, state: {state}")

    def on_connect(self, controller: Controller):
        print(f"connected to controller: {controller}")
        self.ims.append(InputManager.from_existing(self.default_input, controller))

    def on_disconnect(self, controller: Controller):
        pass

    def on_update(self, delta_time: float) -> bool | None:
        for im in self.ims:
            im.update()


if __name__ == '__main__':
    Window().run(MyControllerView())

Pressing dpad should print out directions like for the buttons.

Actual behavior

Only buttons trigger an action.
