[DevTools Bug]: Incorrect source location after hot reload & editing props

Website or app

https://gist.github.com/kiootic/54986cd163b52cbbcd5d8283eb5ed06f

Repro steps

1. Create a new react app using create-react-app
2. Replace the code in App.js with App.jsx in the gist
3. Start the app and inspect the 3 p elements using dev tool
4. Should observe correct line numbers (App.js:4, App.js:5, App.js:6)
5. In code editor, change the first p element to be multiline, like App-update.jsx in gist
6. After hot reload, should observe updated line numbers (App.js:4, App.js:7, App.js:8)
7. Using dev tool, change the first p element's children prop to be something else.
8. Should observe incorrect line numbers (reverted to App.js:4, App.js:5, App.js:6)
9. Repeat step 7 again, and should observe correct line numbers again.
10. The line numbers are observed to be alternating between correct & incorrect state when repeating the edit step.

Reproduce the issue with the App.jsx and App-update.jsx examples from the linked gist in a create-react-app app, then inspect the three p elements in DevTools. Repeat the hot reload and children-prop edit sequence while comparing the reported App.js line numbers; done means the locations remain correct rather than alternating between states.
