From #102493 (comment)

In this case:

1. The user had Node.js importing a different casing of their file (socks5udp) than what was actually on their disk (socks5UDP).

{
  "source": {
    "name": "socks5UDP.js",
    "path": "c:\\Users\\Rohit Kapoor\\source\\sockem\\lib\\socks5UDP.js"
  },

2. They set breakpoints, VS Code set in socks5UDP
3. We set the breakpoint, and V8 resolved it. V8 used the imported casing socks5udp
4. Then js-debug sent back that the breakpoint in the source, using the casing/path from Chrome

{
  "name": "lib/socks5udp.js",
  "path": "c:\\Users\\Rohit Kapoor\\source\\sockem\\lib\\socks5udp.js",
  "sourceReference": 0
}

5. This caused the breakpoint to move out of its correct file in VS Code

What should be the proper behavior here? Who should canonicalize the path?
