You're right, I should elaborate. The site causes a normal KeePassXC-Browser popup, "www.dailymaverick.co.za has requested access to passwords for the following item(s). Please select whether you want to allow access."

Then comes the weird stuff. It may not actually be all my passwords, but it sure is a lot of them, the long list ominously beginning with my bank and a mobile payment solutions.

It's probably a bug of some kind. But sure looks scary.

On my way to work, and on phone only for next many hours, so not able to look further into.
