### Godot version

v4.0.beta.custom_build [705273140]

### System information

windows 10

### Issue description

When double-clicking a gltf file in the project, the Importer panel will open, but it will also extract the embedded textures.
This never happened in the previous version I was using (I'm not sure which beta I was using last- maybe 13 or 14).



### Steps to reproduce

open the project, and double-click the gltf file to open the importer, see that it creates an image file when it should stay embedded.
