-- END OF BACKTRACE --

I didn't look into what causes it, just found some random 100% repro.

Steps to reproduce

1. Download the MRP from New TileMap editor: Tilemap creates kind of layereffect at the edge of the y-axis when painting a tile #57266
2. Click the TileMap
3. Copy the TileSet
4. Clear the TileSet
5. Paste the TileSet
