Devtools cause hydration error #1726
Description
Describe the bug
The devtools cause a hydration error because the state values that depend on localStorage are not equal to the state values returned from the server. We should make sure that these state values are only set after the client has mounted, so on a useEffect() and not a direct call to localStorage.

To Reproduce
Add dev client, have something in localStorage, refresh.
Expected behavior
No hydration error.
