[Video] Bug

STEPS:
1. Create a React app with https://reactjs.org/docs/create-a-new-react-app.html#create-react-app
2. Inspect it with Web Inspector
3. Open App.js in Sources
4. Click on the line gutter to set a breakpoint inside of App()
5. Reload page

EXPECTED:
Debugger stops on the breakpoint.

ACTUAL:
Debugger didn't stop on the breakpoint.

NOTES:
Note that `debugger` statements still work.

Note this also doesn't work in Chrome DevTools but works in Firefox DevTools.
