error occurs on removing hotkey while binding one function to two keys

import keyboard

def func():
    # do something
    print("something")

remove_func1 = keyboard.add_hotkey("o", func)
remove_func2 = keyboard.add_hotkey("p", func)

# current keyboard._hotkeys
# {'o': <function keyboard.add_hotkey.<locals>.remove_()>,
#  <function keyboard.add_hotkey.<locals>.remove_()>: <function keyboard.add_hotkey.<locals>.remove_()>,
#  <function __main__.func()>: <function keyboard.add_hotkey.<locals>.remove_()>, # !!Notice here
#  'p': <function keyboard.add_hotkey.<locals>.remove_()>,
#  <function keyboard.add_hotkey.<locals>.remove_()>: <function keyboard.add_hotkey.<locals>.remove_()>}

remove_func1() # or keyboard.remove_hotkey(remove_func1) or keyboard.remove_hotkey("o")
# current keyboard._hotkeys
# {'p': <function keyboard.add_hotkey.<locals>.remove_()>,
#  <function keyboard.add_hotkey.<locals>.remove_()>: <function keyboard.add_hotkey.<locals>.remove_()>}

# !!this step raise KeyError
remove_func2() # or keyboard.remove_hotkey(remove_func2) or keyboard.remove_hotkey("p")

seems using dict.pop(key, None) to replace del dict[key] might helps
