The underlying issue extends to all frozen modules.  I've opened #25268 to 
consider how we might address it.

[issue21335] Update importlib.__init__ to reset _frozen_importlib's loader to SourceFileLoader

[Brett Cannon]

Brett Cannon added the comment:

Even with setting SourceFileLoader, you still don't get file lines back. Why? 
Because all of the constructed objects in _frozen_importlib have their 
co_filename set before the back-patching in importlib.__init__ and so when the 
traceback module tries to do its thing it sees '' 
as the filename instead of importlib._bootstrap.__file__ which doesn't lead to 
linecache getting anything useful.

IOW a whole lot of effort for code that people should never have to look at.
