OS/Web Information

• Web Browser: Chrome
• Local OS: window 10
• Remote OS:CentOS7
• Remote Architecture:
• code-server --version: 4.11

Steps to Reproduce

1. When open url such as http://127.0.0.1:8010/?folder=/home/lhdu/kbdev/aistudio-test&payload=[[%22openFile%22,%22vscode-remote:///home/lhdu/kbdev/aistudio-test/b.ipynb%22]],sometimes rendered as json 2.Personal speculation: OpenFile behavior is activated earlier than the ipynb extension, or the activation time of the ipynb extension is too long 3.There is a small probability of it appearing when refreshing the browser

Expected

always render as jupyter-notebook

Actual

sometimes render as json

Could you test this in Codespaces as well? Seems like the sort of thing that could be an upstream bug.
