We should always show the local and session storage items in the Storage panel. They should also have an empty datagrid so you can insert new values from the UI without havign to poke it with the console first.
This is tricky because they are not added into the Web Inspector until they are accessed (if a script calls localStorage, or someone types something in the Console, and it tries to autocomplete to localStorage. I am not sure the best way to solve this, but would be open to suggestions. One thing that should be more straightforward, and I will work on is showing an empty datagrid instead of a "This Storage is Empty" view, since local and session storage are now R/W from the inspector.

Old bug. What's the status here Brian?
It works correctly at me. I will close the bug if noone would mind.
