JB default instead Atom icon for .py file icon is shown on the sidebar in PyCharm 2024.2

[mhxion]

Describe the bug

Atom icon for .py file extension is correctly shown on the opened tab, but not on the sidebar (file icon association has not been changed of course), on an existing project.

Oddly enough, the bug cannot be reproduced with other file associations like with .js files!

To Reproduce

1. Update PyCharm to 2024.2
2. Open an existing project
3. Create a .py file

Expected Behavior

It should show the Atom Python icon.

I had the same issue for a few months no matter whether it was 2023.x.x or 2024.x.x IDEs. It also seems, that the same issue persists with the installation of Classic UI plugin, so it doesn't seem related to the UI stye.

Unless the plugins collide in my case, and the Classic UI takes precedence over Atom Icons, but I doubt that, since the OP has New UI.

Example of how it looks with Classic UI plugin:

An instance of the built-in icons can also be found in the File Types settings - I don't know if it affects the issue somehow though.
