issue-5523

Steps to reproduce

1. Create a vue app.
2. Add Firebase using yarn add firebase
3. Replace the code of main.js file.
4. Run the program with yarn serve.

Noticed behavior

• Initial run will work as intended. However, as mentioned by the developer, if you'll add a new data you'll encounter this error:

Uncaught TypeError: newChildren.insert is not a function

• Tried running the same code in react and it is working as intended.
