lazy import breaks google-auth library

[racinmat]

Using https://pypi.org/project/google-auth/ and

import google.auth.transport._http_client
google.auth.transport._http_client.Request()

works, but when I lazy-load the google-auth, like this

import lazy_import
lazy_import.lazy_module("google.auth")
import google.auth.transport._http_client
google.auth.transport._http_client.Request()

I get AttributeError: module 'google.auth.transport' has no attribute '_http_client'. Did you mean: 'http_client'?

The same issue happens on the https://github.com/gdb/lazy_import fork, which is registered as https://pypi.org/project/lazy-import-plus/, too.
