python - pyppeteer 命令改变窗口大小 [bug??]

Question

我正在开发一个需要使用 pyppeer 来控制铬实例的程序。当我使用返回按钮时，我遇到了麻烦，窗口的大小被改变了。我该如何防止这种情况发生？

这是我的代码的缩短版本

import pyppeteer
import asyncio
import threading
import subprocess 
import tkinter as tk

class ThreadedInstance():
    def __init__(self, command):
        self.ThreadingCommand = lambda: subprocess.run('{}'.format(command), shell = True)
        self.Thread = threading.Thread(target = self.ThreadingCommand)
        self.Thread.start()

def createInternet():
    internet = ThreadedInstance('chromium-browser --start-fullscreeb --start-maximized --remote-debugging-port=9222 www.google.com')
    global browser
    global page
    async def main():
        browser = await pyppeteer.connect(browserURL='http://127.0.0.1:9222', autoclose=False)
    asyncio.get_event_loop().run_until_complete(main())

class GUILocate():
    def __init__(self):
        self.root = tk.Tk()
        self.root.overrideredirect(True)
        self.root.geometry('100x100')
        self.backwardsButton = tk.Button(self.root, text = 'Back')
        self.backwardsButton.place(x=0, y=0, width = 100, height = 100)
        self.backwardsButton.config(command = lambda: asyncio.get_event_loop().run_until_complete(self.goBack()))
        self.root.mainloop()
    async def goBack(self):
        browser = await pyppeteer.connect(browserURL='http://127.0.0.1:9222', autoclose=False)
        pages = await browser.pages()
        currentPage = pages[0]
        await currentPage.goBack()

        

if __name__ == '__main__':
    createInternet()
    locate = GUILocate()
