Qt Designer проблема со scrollBar, который не хочет нормально отображаться, когда использую StyleSheet

Я использую PySide2, хотя и в PyQt5 такая же проблема.

Ссылка, откуда я брал раскраску скролла (Если вдруг поможет):

https://www.youtube.com/watch?v=ttBjf4bMDXY&t=627s&ab_channel=Wanderson

Когда я запускаю test.ui* в QT Designer, проблема со скролом в stylesheet нет нигде, а когда я запускаю через main.py, то в TextEdit и PlainTextEdit не отображается нормально scrollbar (На картинке будет видно):

Как решить эту проблему?

Вот код каждого файла:

main.py:

import sys
from PySide2 import QtCore, QtGui, QtWidgets
from PySide2 import QtLocation
from PySide2.QtGui import QClipboard
import PySide2.QtWidgets
import PySide2.QtCore
from windowtest import Ui_Dialog
class main(QtWidgets.QMainWindow): 
    def __init__(self): 
        super(main, self). __init__()
        self.windowtest = Ui_Dialog()
        self.windowtest.setupUi(self)
if __name__ == "__main__":
    app = QtWidgets.QApplication([])
    application = main()
    application.show()
    sys.exit(app.exec_())
#pyside2-uic test.ui -o windowtest.py

После я перевёл test.ui в windowtest.py с помощью pyside2, командой в консоли:
