Web Installer bug report

Hello I am not sure to which project nextcloud-setup.php belongs to report a bug.

step 1 No Problem

step 2 Enter a single “.” to install in the current directory, or enter a subdirectory to install to:

selecting ‘.’ is no problem

if I leave it as is ‘nextcloud’ there comes a issue when redirecting to index.php as it redirects without domain.tld to https://nextcloud/index.php where as when I choose ‘./nextcloud’ as installatiion directory it redirects correctly

should ‘./nextcloud’ not be set as default. Where is this file on github or will someone here pick it up.
