Choose that workspace as the current workspace. Note that localstorage does actually update the value of earthstar-peer-status-current-workspace
Reload the page. It will not remember which workspace you were viewing, it will instead say "Add workspace" in the dropdown even though localStorage knows which one you should be viewing.
Sign in as a user, and now it will remember the current workspace when you reload.
To reproduce:
earthstar-peer-status-current-workspace
