The operator (written in C) does not use the context to find selected objects.
I'm not sure if this can be considered a bug.

On second thought, whether in C or Python, operators are not required to use context to perform their operations.

Even if the context's "selected_objects" are overwritten, Object.select_get() is not affected (and is used for eg save or undo).

You can confirm this with this code:

import bpy

obs = [bpy.data.objects["Sphere"]]

with bpy.context.temp_override(selected_objects=obs):
    print(bpy.context.selected_objects[0].select_get())

We could change specific operators to give preference to context, but even then not using them is not necessarily considered a bug.

So, unless you intend to work on this operator (proposing patches), as this report is not about a bug or error, I am closing it.
