Why is console.log() showing react_devtools_backend.js:4049 instead of the file and line number?

I was able to fix it in my console by adding the file to my Framework Ignore List in Chrome.

Console -> Gear icon (top right) -> Settings -> Framework Ignore List.

Add react_devtools_backend.js to the list and the console.log should start showing the correct mapping again.
