Short description of error
working with scenes and exporting to gltf is ignoring which scene is active and which collections are active.
active collections are used to filter what gets exported for fbx, the same behavior should happen with gltf. as is, all assets in the first scene in the .blend file and all objects are exported regardless weather the collection is active/innactive or how many other scenes are in the .blend file.
it should only export from the active scene (not the first) using the active collections.
Exact steps for others to reproduce the error
create two collections add objects to both. deactivate one collection. export. (bug) all objects will export.
create two scenes add objects to both. activate second scene. export. (bug) only objects from first scene will export.
