Research direction
Start by reproducing the issue using the VS Code “Your First Extension” guide and compare the behavior with Codespaces. Read the linked discussion at https://github.com/coder/code-server/discussions/7423, then trace the debugger connection and extension activation in the new window. Done means the debugged extension appears and is active there.
Written by the indexing model from the issue text.
Description
When you debug an extension it opens a new window with that extension active. However, the extension appears to be completely missing in the new window, even though the debugger appears to be logging a connection. It works as expected in Codespaces.

I am simply following https://code.visualstudio.com/api/get-started/your-first-extension and hit "Debug: Start Debugging" a new window opens up and debugger is happy, but I do not see the new extension in the new code-server that opens. Has anyone done this recently, and if so what do I need to do?
