Tested versions

• Reproduciple in: 4.1.x (tested at least in 4.1.3 and 4.1.4)
• Not reproducible in: 4.2.1, 4.2.2

System information

Godot v4.2.2.stable - macOS 14.4.1 - Vulkan (Forward+) - integrated Apple M3 Pro - Apple M3 Pro (12 Threads)

Issue description

TileMaps set_cell function does not delete tiles that use scenes collection as described in documentation:

If source_id is set to -1, atlas_coords to Vector2i(-1, -1) or alternative_tile to -1, the cell will be erased. An erased cell gets all its identifiers automatically set to their respective invalid values, namely -1, Vector2i(-1, -1) and -1.

Steps to reproduce

• Add scene to tileset scene collection.
• Use code to add as tile to tilemap
• Try to erase cell with set_cell:

tile_map.set_cell(0, position)
tile_map.set_cell(0, position, -1, Vector2(-1, -1), -1)
tile_map.set_cell(0, position, -1, Vector2(-1, -1), 0)
tile_map.set_cell(0, position, -1, Vector2(0, 0), -1)
tile_map.set_cell(0, position, -1, Vector2(0, 0), 0)
tile_map.set_cell(0, position, 0, Vector2(-1, -1), -1)
tile_map.set_cell(0, position, 0, Vector2(-1, -1), 0)
tile_map.set_cell(0, position, 0, Vector2(0, 0), -1)

In MRP use left mouse button to add tiles and right mouse button to delete.

Since this has been fixed in 4.2 and 4.1 is possibly not going to receive any more fixes, the solution is to upgrade to 4.2

Ok. I'm kind of stuck between this and problems with touch on 4.2.x: #88621. :/

A fix for 4.1.x is unlikely to happen sooner than a fix to that bug I'd say, if any fix is cherry picked for 4.1 at all, hard to tell without knowing what fixed the issue in the first place
