add_updater does not correctly retrieve the objects' name introduced in main file when embed with OpenGL.

[ChungLeeCN]

When I enter the interactive mode through self.interactive_embed() with OpenGL, all objects imported in the main program, custom variables, and objects cannot be used within the add_updater. Here is an example: even though from manim import * has been used to import all Manim objects in the main program, using Dot in always_redraw is considered undefined.
