Breakpoints move up 10 lines when debugging jest tests

[makr28]

Issue Type: Bug

I am working on a Node.js project with Jest unit tests. I am using the launch configuration i've pasted below to run the jest tests. If I put a break point on line 280, when I run the debugger the break point is now on line 270.

This did not happen on the older version of VS Code I had on my previous laptop (a Lenovo Thinkpad w541) And began only once I got a new laptop (Dell precision 5530) and installed the current version of VS Code.

My Launch Configuration
{
"type": "node",
"request": "launch",
"name": "Jest Tests (Windows)",
"program": "${workspaceRoot}\node_modules\jest\bin\jest.js",
"args": ["-i"],
"internalConsoleOptions": "openOnSessionStart",
"outFiles": ["${workspaceRoot}/dist/**/*"]
}

VS Code version: Code 1.28.1 (3368db6, 2018-10-11T18:13:53.910Z)
OS version: Windows_NT x64 10.0.17134
