Godot 4.1.1 gridmap doesn't update from meshlibrary properly when saving meshlibrary as .tres file

[elvisish]

Godot version

4.1.1 stable

System information

Windows 10

Issue description

Updating the gridmap meshlibrary scene and updating the meshlibrary changes the scene in the editor, but doesn't reflect the changes when running the scene or re-opening it:

Steps to reproduce

• Create a gridmap scene
• Create a meshlibrary from the gridmap scene
• Change the transforms on a mesh in the gridmap scene
• Update the meshlibrary
• Run the scene/reopen the scene and see the changes reverted

FIX: don't save the meshlibrary as a .tres file, keep it embedded in the scene:

I wonder if the MeshLibrary resource needs to be updated when the Gridmap is updated, perhaps the changes are just not being saved back to the resource file?

Can't reproduce in 4.2.

@elvisish Can you check if it's also fixed for you in 4.2-rc1 or later?

It seems to be fixed, I'm not sure why it didn't stick the first time but it looks good to go now in RC1.
