Description / Steps to Reproduce [if necessary]

When a QTableWidgetItem is set to "isUserCheckable" the checkbox that comes with it is not in the style of qdarkstyle, but rather in the default style (white box with black check mark). This only holds for QTableWidgetItem; the checkbox of e.g. a QListWidgetItem is in the qdarkstyle (see example below).

Actual Result

Expected Results / Proposed Result

The checkbox of a user-checkable QTableWidgetItem should be in the same style as the other checkboxes in qdarkstyle.

Relevant Code [if necessary]

Minimal example which produces the image above:

import sys
from PyQt5 import QtWidgets, QtCore
import qdarkstyle

class Window(QtWidgets.QWidget):
    
    def __init__(self):
        super().__init__()

        self.table = QtWidgets.QTableWidget()
        self.table.setColumnCount(1)
        self.table.setRowCount(1)
        table_item = QtWidgets.QTableWidgetItem('Table item')
        table_item.setFlags(table_item.flags() | QtCore.Qt.ItemIsUserCheckable)
        table_item.setCheckState(QtCore.Qt.Checked)
        self.table.setItem(0, 0, table_item)
        
        self.list = QtWidgets.QListWidget()
        list_item = QtWidgets.QListWidgetItem('List item')
        list_item.setFlags(list_item.flags() | QtCore.Qt.ItemIsUserCheckable)
        list_item.setCheckState(QtCore.Qt.Checked)
        self.list.addItem(list_item)        
        
        layout = QtWidgets.QVBoxLayout()
        layout.addWidget(self.table)
        layout.addWidget(self.list)
        self.setLayout(layout)  
        self.show()                  
            
app = QtWidgets.QApplication(sys.argv)    
app.aboutToQuit.connect(app.deleteLater)
app.setStyleSheet(qdarkstyle.load_stylesheet_pyqt5())

w = Window()
app.exec_()
