### Godot version

4.1 beta1

### System information

Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 (NVIDIA; 30.0.15.1403) - Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 Threads)

### Issue description

When I change tile source, the view is initialized at a wrong position. After scrolling it for the first time, the position gets re-adjusted.

It wasn't happening before.

### Steps to reproduce

1. Create a TileMap with TileSet
2. Add a sufficiently big tile atlas source
3. Add another source, so that you can switch between the 2
4. Switch to the other source and then to the big one
5. Scroll
