 The code below from `wp-includes/js/dist/preferences-persistence.js` tries
 to make a REST API call to '/wp/v2/users/me?context=edit', even when not
 logged in. On my site, this returns a 401 (maybe due to a security
 setting).

 Would it not be possible to check whether the user is logged in first,
 either through some WP JS data or a JS cookie, and not do this call if the
 user is not logged in?

 {{{
 function create({
   preloadedData,
   localStorageRestoreKey = 'WP_PREFERENCES_RESTORE_DATA',
   requestDebounceMS = 2500
 } = {}) {
   let cache = preloadedData;
   const debouncedApiFetch =
 debounceAsync((external_wp_apiFetch_default()), requestDebounceMS);
   async function get() {
     if (cache) {
       return cache;
     }
     const user = await external_wp_apiFetch_default()({
       path: '/wp/v2/users/me?context=edit'
     });
 }}}
