### Godot version

4.2

### System information

Godot v4.2.stable - Windows 10.0.19045 - Vulkan (Mobile) - dedicated AMD Radeon RX 6700 XT (Advanced Micro Devices, Inc.; 31.0.21001.45002) - AMD Ryzen 5 3600 6-Core Processor (12 Threads)

### Issue description

Tiles with light occluders still show shadows, when replacing them by code (set_cell) with a not occluding tile.
This does not happen when they are replaced with an empty cell (cell_id = -1) or erase_cell.

### Steps to reproduce

Make a new project with a Tilemap2D and a PointLight2D
Make 2 Tiles: One with an occluder and one without
Make the tiles placed by code.
Replace an occluding tile with a non occluding
