• [X] I have searched the existing issues

OS/Web Information

• Web Browser: Safari
• Local OS: macOS 14.5
• Remote OS: Ubuntu
• Remote Architecture: x86_64
• code-server --version: 4.89.1

Steps to Reproduce

1. Put code-server behind nginx
2. Access through nginx

Expected

Syntax highlighting should work the same as it does without Nginx.

Actual

Syntax highlighting is very basic when running behind Nginx, leaving most of the code white.

Accessing through Nginx

Accessing without Nginx

Does this bug reproduce in native VS Code?

No, this works as expected in native VS Code

Does this bug reproduce in GitHub Codespaces?

I did not test GitHub Codespaces

Are you accessing code-server over a secure context?

• [X] I am using a secure context.

Notes

When accessing without Nginx, I am accessing over an insecure context. Nginx is being used to add SSL to the connection.
