Frontend "npx webpack --watch" only reflected on localhost but not 127.0.0.1

[amrlafi]

Describe the bug
On local development, Django starts on 127.0.0.1:8080, however npx webpack --watch only respects localhost:8080

To Reproduce
Steps to reproduce the behavior:

1. Load Label Studio locally python3 label_studio/manage.py runserver, Label Studio will be served on 127.0.0.1:8080
2. Go to the frontend directory and run npx webpack --watch
3. Changes in React code will not be reflected until you open label Studio on localhost:8080

Expected behavior
Changes should be also visible on 127.0.0.1:8080

Environment (please complete the following information):

• OS: Mac OS Big Sur
• Label Studio Version: 1.0
