TileMap hangs on loading .tscn

### Tested versions

v4.2.stable

### System information

Apple M1 OS version: 14.3 (23D56)

### Issue description

I cannot load a tilemap almost 90% of the time. It can be either load and hang on adding properties on tileset or it will just not load or draw. TileMap is not that big ~200 tiles

### Steps to reproduce

Load project, load tilemap or edit tileset to some extent.

### Minimal reproduction project (MRP)

Project:

Start by downloading the linked minimal reproduction project and reproduce the hang on Apple M1 with Godot v4.2.stable. Load the project, open the TileMap or edit its tileset, and observe whether the .tscn loads and draws or hangs while adding tile properties. Done means the reproduction no longer hangs or fails to load under the reported steps.
