Issue with a folder full of ~500 untrusted files

[StefanBrand]

Hi, I have a folder with 469 untrusted files. When I navigate to that folder, the logs are spammed with messages like these:

[W 2021-06-24 07:51:28.229 SingleUserNotebookApp manager:510] Notebook <path>.ipynb is not trusted
[I 2021-06-24 07:51:28.238 SingleUserNotebookApp log:189] 200 GET <api-path>.ipynb?1624521002346 ([email protected]) 42898.22ms

The Kubernetes pod becomes unresponsible at this moment and already open notebooks show Connecting because they cannot reach the kernel anymore.

It seems that the extension is trying to access all files. I don't see why it would do that, though. In any case it leads to severe performance problems and makes the Jupyter server unresponsive.
