3D models do not load after first start of layout

Bug: 3D models do not load properly after first start of layout. I.E. If layout is restarted, and if game is saved then loaded later.

Steps to Reproduce:

1. Import 3d model(.glb) into 3d Models folder

2. Create 3d model plugin and make sure model is selected properly for it to display it in viewport/layout when placed.

3. Place 3D model in viewport/layout and see it displaying properly in viewport/layout.

4. Start game from editor

5. Notice that 3d Model loads properly

6. restart layout(by death, or by saving then loading, or any other method while in-game to restart layout).

7. Notice that 3d Models did not load.

Note: Attempted Persist behavior on 3d model plugins/objects and anything associated with them with no luck getting them to load after layout restart. Also exported to Windows(webview2) and launched EXE for it. 3d models did not load for that either on initial launch.
