This is still the case in the invoice emails I receive from [email address removed] even now. The computer program that writes invoices and emails them is very outdated and in 2024 I would even call an "http-no-'s'://" URL a bug. It has been known for a very long time that even moderately important web addresses should be linked using https instead of http. Just file a bug report, get someone to find it and fix it.
