Non-package module loaded from ModInfo object retains __path__ from previously loaded package.

Bug report

Assume you have two separate modules with the same name. One is a package, one is not.

Use pkgutil.itermodules to get a ModuleInfo object for the package, then load the it using find_module and load_module. This object has a __path__ object with the location of package, as expected.

Next, do the same for the non-package module. The resulting module object should have no __path__ attribute, but instead it has one with the location of the package opened previously.

This can be replicated with a structure such as \module\submodule\submodule.py, using \module and \module\submodule as the arguments for the two calls to pkgutil.itermodules.

Your environment

• CPython versions tested on: 3.10.7, 3.11.0rc2
• Operating system and architecture: Windows 10

issue に記載された 2 つのモジュールレイアウトで、pkgutil.itermodules に続けて find_module と load_module を使用して動作を再現します。package と non-package のモジュールオブジェクトを比較します。完了条件は、non-package モジュールが以前に読み込まれた package の path を保持しなくなることです。
