Summary

Previously, __init__.py in pages would be invisible to autogenerated navigation. After an upgrade (and after testing with several versions), somewhere between 1.43.1 and 1.44.1, this behavior changed and now there is a blank "init" page in the navbar.

Reproducible Code Example

Steps To Reproduce

Can be reproduced by setting up a structure like so, and running streamlit run mainpage.py on 1.43.1 vs 1.44.1:

.
└── appname/
├── appname/
│ ├── pages/
│ │ ├── init.py
│ │ ├── page1.py
│ │ └── page2.py
│ ├── mainpage.py
│ └── init.py
├── README.md
└── poetry.lock

Expected Behavior

Expected that __init__.py/"init" should not be listed in pages.

Current Behavior

1.43.1:

1.44.1

Is this a regression?

• Yes, this used to work in a previous version.

Debug info

• Streamlit version: 1.44.1
• Python version: 3.10.12
• Operating System: Ubuntu/Docker
• Browser: Edge
