Steps to reproduce the problem:
1. Open a website that works with localstorage API.
2. Open devtools.
3. Check LocalStorage

What is the expected behavior?
Must show both website storage and chrome-extension local storage.

What went wrong?
Website local storage appears at first but I check other tab, for example network traffic and go back to localStorage, the website's localStorage is not visible.
To make it visible I must close DevTools and open it again.

Did this work before? N/A
