Context: I am using python to automate exporting a number of GLTF files from various objects stored in different scenes in my .blend file. For each of the exports, my code uses context.temp_override(scene=...) to make the appropriate scene active, then invokes bpy.ops.export_scene.gltf(use_active_scene=True, ...).

After invoking bpy.ops.export_scene.gltf(), the currently active scene in the UI is changed to the scene that I passed into temp_override(). This is particularly annoying when I am in a workspace with a pinned scene, as the export changes which scene is pinned.

This seems to be due to: gltf2_blender_gather.py lines 36-48:

    store_user_scene = bpy.context.scene
...
    # restore user scene
    bpy.context.window.scene = store_user_scene

Ideally the GLTF export ought to be using temp_override() itself instead of changing the context. But at least to ensure the export restores the same scene as was in the window beforehand, line 36 ought to be:

    store_user_scene = bpy.context.window.scene
