Entities are not registered for models loaded using GLTFLoaderPlugin

[jbenhardus]

Is this bug fix critical for your commercial enterprise?
We have potential workarounds, but this affects required functionality for our application

Describe the bug
When loading a model in .glb or .gltf format, scene. objects is empty. This prevents the use of methods and properties such as scene.objectIds and scene.setObjectsVisible to show or isolate objects in the scene.

To Reproduce
Steps to reproduce the behavior:

1. Load a model using GLTFLoaderPlugin, providing urls for src and metaModelSrc
2. Inspect viewer.scene.objects using a breakpoint or console log statement
3. viewer.scene.objects is empty and scene.setObjectsVisible does not change visibility of objects

Expected behavior
viewer.scene.objects should be populated, and scene.setObjectsVisible should update the visibility of objects

Desktop (please complete the following information):

• OS: MacOS 14.4.1
• Browser: Chrome
• Version: 125.0.6422.61

Additional context
It appears the issue arises because the loadNode function in GLTFSceneModelLoader calls sceneModel.createEntity without specifying the isObject property in the config object (example here). Adding isObject: true to the config fixes the issue I am experiencing

This should be OK now in the latest xeokit-sdk release - please try that and close this issue if it looks good.

Thanks! This seems to be working as expected now.
