Facility to keep breakpoints within the editor

I tried vscode-chrome-debug (https://github.com/Microsoft/vscode-chrome-debug) to set breakpoints in the editor itself. This is my launch json:
`{
"name": "Launch localhost with sourcemaps",
"type": "chrome",
"request": "launch",
"url": "http://localhost:4200",
"sourceMaps": true,
"webRoot": "${workspaceRoot}"
},`

I was able to launch chrome and run the app, but the breakpoints set had no effect. When I used a _debugger_ statement inside the app, the VSC stopped at the statement in _app-name.js_.

It'd be nice to have this feature for it's cumbersome (slightly) to go to Chrome and search for that file there.

Great extension btw.
