Certain meshes produce merge_with : AABB size is negative

Issue description

Certain meshes produce the title.

The reproduction project has a model which produces this issue. I have no clue how to recreate this. All I know, is that for some models that I create, I will get this issue. I use blender to create my models.

I use a variety of modifiers, techniques, etc., so I am unsure of what I could be doing that would cause this.

This causes massive error spam when reusing models (think 20-50 characters x 4 errors)

Steps to reproduce

No applicable steps atm. Only the model in the reproduction project. I can look to provide more model examples if need be.

I think it's a duplicate of #56458, but may be caused by different reason (since the model you've provided should not have bones since its *.OBJ ?)

[stryker313]

The model I provided comes from an imported GLTF file with a skeleton. I simply seperated it from the original scene.
However...
Interesting discovery.

Based on @Chaosus comment, I imported the mesh into blender, used a cube with intersect boolean, reimported into Godot, and the error dissapeared.

This project contains a second scene, with the model that has the AABB error disappeared.

I'm getting this error as well with a .blend file (which converts to GLTF under the hood)

I created the mesh + skeleton with makehuman.

This is running on pretty recent mainline (beta 11 or just before that).
