Created attachment 410286 [details] [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.
