title: Why is console.log() showing react_devtools_backend.js:4049 instead of the file and line number?
body: <p>When I <code>console.log()</code>, the Chrome console gives the log but instead of showing the file and line number it just says <code>react_devtools_backend.js:4049</code>. How do I get the console to show the file and line number when I <code>console.log()</code>?</p>
