Comment (by SergeyBiryukov):

 In [changeset:"48869" 48869]:
 {{{
 #!CommitTicketReference repository="" revision="48869"
 Upgrade/Install: Make the check for empty `home` option in
 `__get_option()` more resilient.

 This addresses a regression in [47808], where the `home` check expected an
 empty string to use `siteurl` as a fallback, but `wpdb::get_var()` returns
 `null` if the option is empty.

 Props fjarrett.
 Merges [48868] to the 5.5 branch.
 Fixes #51011.
