[Python] How to update Folium map without re rendering entire map?

I have a Folium map placed in PySide6 QWebEngineView. Map coordinates are updated each second and the map is recentered to the new position. However, this is re-rendering entire map with each update and it causes "flashing", which is not user friendly.

I need to make the map to reposition by smooth dragging/sliding, or even jump will be fine if flashing does not happen. I could not find any real solution for it anywhere.

This is the code I have in map.py:

import io
import sys
import folium
from PySide6.QtCore import QTimer
from PySide6.QtWebEngineWidgets import QWebEngineView
from PySide6.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QWidget


class MapWebView(QWebEngineView):
def __init__(self, initial_coordinates: tuple[float, float]):
super().__init__()
self.folium_map = folium.Map(
location=initial_coordinates,
zoom_start=13,
zoom_control=False,
attribution_control=False
)
self.data = io.BytesIO()
self.folium_map.save(self.data, close_file=False)
self.setHtml(self.data.getvalue().decode())

def update_map(self, new_coords: tuple[float, float]):
self.folium_map = folium.Map(
location=new_coords,
zoom_start=13,
zoom_control=False,
attribution_control=False
)
self.data = io.BytesIO()
self.folium_map.save(self.data, close_file=False)
self.setHtml(self.data.getvalue().decode())


class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.resize(600, 600)
self.setCentralWidget(QWidget())
self.centralWidget().setLayout(QVBoxLayout())

self.map_webview = MapWebView((47.030780, 8.656176))
self.centralWidget().layout().addWidget(self.map_webview)

timer = QTimer(self)
timer.timeout.connect(self.update_map)
timer.start(1000)

def update_map(self):
current_coords = self.map_webview.folium_map.location
new_coords = (current_coords[0] + 0.002, current_coords[1] + 0.002)
self.map_webview.update_map(new_coords)


if __name__ == '__main__':
app = QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec())
