Changing background opacity causes stacktrace

[sandervankasteel]

When you try to change the background opacity of the window, you get a stacktrace back.

Traceback (most recent call last):
  File "/usr/bin/../lib/kitty/kitty/boss.py", line 283, in _handle_remote_command
    response = handle_cmd(self, window, cmd)
