When I do plt.figure in PySimpleGUI, the window shrinks.

If I create a figure object with matplotlib.pyplot while using PySimpleGUI, the window size of the application created with PySimpleGUI will be fixedly reduced. Is there any way to avoid this?

Run Environment
Python 3.10.2
matplotlib 3.5.1
PySimpleGUI 4.57.0
Windows 11 Home(21H2)
Intel® Core™ i5-1035G4 [email protected] 1.50GHz

source code

import PySimpleGUI aspg
import matplotlib.pyplot asplt

layout = [
    [pg.Button(key='-button-', button_text='')]
]

window=pg.Window('demo', layout, size=(800,600))


while True:
    event,_=window.read()

    if event==None:
        break
    if event=='-button-':
        plt.figure()
