### 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.

		const Dictionary &d = textures[i];
		ERR_FAIL_COND_V(!d.has("source"), ERR_PARSE_ERROR);
		Ref<GLTFTexture> t;
		t.instantiate();
		t->set_src_image(d["source"]);
		if (d.has("sampler")) {
			t->set_sampler(d["sampler"]);

			t->set_sampler(-1);
		}
		p_state->textures.push_back(t);
	}
	return OK;
