localhost openExternal rewrite loses URL /path

从 patches/proxy-uri.diff 和报告中确定的 resolveExternalUri 调用开始；使用 browser.sh 命令和包含 /my/path 的 URL 重现该行为。检查重写后的 URL 如何处理路径，然后也验证查询参数和锚点。重写后的代理 URL 保留原始 URL 后缀即表示完成。

Is there an existing issue for this?

OS/Web Information

• Web Browser: chrome
• Local OS: macOS
• Remote OS: Linux/Ubuntu
• Remote Architecture: amd64
• code-server --version: 1.107.0

Steps to Reproduce

1. /usr/lib/code-server/lib/vscode/bin/helpers/browser.sh http://127.0.0.1:1234/my/path
2. Opens URL https://coder.<domain>/@<user>/<instance>/apps/code-server/proxy/1234/
3. Be saddened by the observation that /my/path was dropped during the rewrite.

Expected

Should have rewritten to URL https://coder.<domain>/@<user>/<instance>/apps/code-server/proxy/1234/my/path (with trailing /my/path). When I update the URL in my browser to do this, this works - so the proxy itself is doing all the right things, it's just the rewrite that is incorrect afaics.

I have not explored with query params or anchors. Given what I see in the code, I suspect these are lost too.

Actual

Opened URL https://coder.<domain>/@<user>/<instance>/apps/code-server/proxy/1234/

Notes

I believe the relevant code is part of this code-server patch, and not vscode:
https://github.com/coder/code-server/blob/main/patches/proxy-uri.diff

From a squint at this patch, I think the new URL(renderedTemplate, window.location.href) call in resolveExternalUri is suspect. I don't see anything here that would copy through anything after the host portion of the URL.
