<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Upgrade/Install: Make the check for empty `home` option in `__get_option()` more resilient.
This addresses a regression in <a href="https://core.trac.wordpress.org/changeset/47808">[47808]</a>, 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 <a href="https://core.trac.wordpress.org/changeset/48868">[48868]</a> to the 5.5 branch.
Fixes <a href="https://core.trac.wordpress.org/ticket/51011">#51011</a>.</pre>
