size restriction warning for Window minimum height and width being greater than 0 despite setting them correctly

[mz3r0]

Problem:
[WARNING] Both Window.minimum_width and Window.minimum_height must be bigger than 0 for the size restriction to take effect.

In my MDApp.build():

# Window
Window.always_on_top = True
Window.minimum_width = 500
Window.minimum_height = 400
Window.size = (1080, 720)

My kivy-related imports:

# Kivy imports
from kivy.config import Config
from kivy.lang import Builder
from kivy.core.window import Window

# KivyMD imports
from kivymd.app import MDApp
from kivymd.uix.screen import MDScreen
from kivymd.uix.transition import MDSharedAxisTransition

Window restriction works fine. What could be causing this warning?

OS: Windows 10
Python: 3.12
Kivy: 2.3.0
KivyMD: 2.0.1.dev0
