Infinite loop when using shape layers

[chehggg]

What is the bug?

When implementing Flutter_web on Chrome and including polyline, polygon or circle layers with specified LatLng, it throws the below exception when the LatLng is scrolled into view:

Another exception was thrown: Assertion failed: "Infinite loop going beyond 30 for world width 2097152"

The map freezes and the shapes cannot be seen. The error is fired again whenever the map is hovered.

This issue does not exist in Windows app. I do not have other machine so I have not replicate it beyond using Chrome on my current machine. I have tried recreating multiple projects and run flutter clean and flutter pub get but they are result in same error.

How can we reproduce it?

main.dart

import 'package:flutter/material.dart';
import 'package:flutter_map/flutter_map.dart';
import 'package:latlong2/latlong.dart';

void main() {
  runApp(const MainApp());
}

class MainApp extends StatelessWidget /dsadasd
  const MainApp({super.key});

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: MapDrawingScreen(),
    );
  }
}

class MapDrawingScreen extends StatefulWidget {
  const MapDrawingScreen({super.key});

  @override
  State<MapDrawingScreen> createState() => _MapDrawingScreenState();
}

class _MapDrawingScreenState extends State<MapDrawingScreen> {
  MapController? _controller;

  @override
  void initState() {
    super.initState();
    _controller = MapController();
  }

  void onPresssed() {}
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: Row(
          children: [
            Expanded(
              child: MapContainer(),
            ),
          ],
        ),
      ),
    );
  }
}

class MapContainer extends StatelessWidget {
  const MapContainer({
    super.key,
  });

  @override
  Widget build(BuildContext context) {
    return FlutterMap(
      options: MapOptions(
        initialCenter: LatLng(15, 15),
      ),
      children: [
        TileLayer(
          urlTemplate: 'https://tile.openstreetmap.org/{z}/{x}/{y}.png',
          userAgentPackageName: 'com.example.app',
        ),
        PolylineLayer(polylines: [Polyline(points: [LatLng(15, 15), LatLng(10, 12)])]),
        // CircleLayer(circles: [CircleMarker(point: LatLng(10, 10), radius: 5)])
      ],
    );
  }
}

When debugging in Chrome, the map throws the infinity loop error and freezes (because the polyline is in view).
