### 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.

Error err;
	if (p_file.is_null()) {
		return FAILED;
	}
	p_file->seek(0);
	uint32_t magic = p_file->get_32();
	if (magic == 0x46546C67) {
		
		
		p_file->seek(0);
		err = _parse_glb(p_file, p_state);
		if (err != OK) {
			return err;
		}
	} else {
		p_file->seek(0);
		String text = p_file->get_as_utf8_string();
		JSON json;
