Can you unload the sys.path at the end of the function in a finally block?
We do have the case of module name conflicts & want to isolate the modules as
much as possible.

   imp.load_source(
       os.path.splitext(os.path.basename(module_path))[0], module_path)
 
   # Analyze the module for its imports.
   graph = modulegraph.ModuleGraph()
   graph.run_script(module_path)
 
   # Filter for only imports in Chromium.
