Comment (by ocean90):

 [attachment:26511.16.diff]: Changes the check to use `get_user_locale()`
 in admin.

 {{{
 $current_locale = is_admin() ? get_user_locale() : get_locale();
 if ( $current_locale === $locale ) {
     return false;
 }
 }}}

 There is a new test `test_switch_to_site_locale_if_user_locale_is_set()`.
 It's currently failing because `restore_current_locale()` doesn't restore
 `$l10n`. Hmm, that makes actually sense since the value was empty before
 because of `en_US`. Need to test this with another locale…
