Description

I'm using PyQt 5.11.2 for Windows 10 (x64), when the table has more than 1000 rows in it (3000 rows for example), if I hide some of the rows and then call sortItems() or sortByColumn(), those hidden rows with a row number larger than 1001 become visible automatically while others remain hidden. Is this a bug?

A code snippet to reproduce the issue:

import sys

from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *

if __name__ == '__main__':
	app = QApplication(sys.argv)

	test = QMainWindow()

	table = QTableWidget()
	table.setRowCount(3000)
	table.setColumnCount(3)

	for i in range(table.rowCount()):
		table.setItem(i, 0, QTableWidgetItem())
		table.item(i, 0).setData(Qt.DisplayRole, i)

		table.hideRow(i)

	table.sortByColumn(0, Qt.AscendingOrder)

	test.setCentralWidget(table)

	test.show()

	sys.exit(app.exec())
