There was a problem hiding this comment.
These two methods return ValueTask. I'm not sure how often these would return completed tasks, but perhaps we also use value tasks on the new methods on ILocalStorage.

Description
Some UI state is stored in protected browser storage: details orientation and size.
Unfortunately protected storage becomes unusable if the dashboard's data protection keys change. This can happen if the dashboard is launched from a docker container (each run has new keys). I've also seen it when updating Aspire version - perhaps the dashboard being located in a different place or a different file name causes new keys? IDK.
The fix is to store long term (localStorage) non-sensitive state without protected. Values will be remembered between runs, and there won't be errors silently thrown in the background when attempting to unencrpyt and failing.
Short term storage (sessionStorage) that is used to store potentially sensitive page data still only allows storage with protection.
I'll double check this is safe with Blazor and security folks.
Fixes #4949
