3D assets: GLTF files don't autoupdate on reimport, while GLB does

[golddotasksquestions]

Godot version

3.3.4 stable, 3.4 stable, 3.4.1 rc1

System information

Win 64, dedicated Nvidea 765M

Issue description

Iterating on 3D assets is crucial to any 3D game development workflow.

I have previously exported gltf2 as *.glb files from Blender, which worked fine: Whenever I make a change in Blender and export over the previous *.glb file, everything in Godot would auto-update as soon as Godot window becomes active.
However now that I tried exporting *.gltf files from Blender, I noticed they don't auto-update, even though they auto-reimport just like the *.glb files.

Possibly related to #38853

Steps to reproduce

1. Open Blender and export the default cube to your Godot project folder as blender_cube.glb as well as blender_cube.gltf
2. In Godot drag and drop both the .glb as well as the .gltf file into the scene.
3. Now go back to Blender and make a simple visual change (like extrude a face of the cube), export again as both blender_cube.glb as well as blender_cube.gltf into your Godot project folder
4. Make Godot the active window and see both files auto reimporting but only the .glb file actually update.

In order for the .gltf to also update you need to save the Godot scene and reopen it.
