Credentials not filling in on konto.flatex.de

The 1Password extension is not suggesting any items to autofill on website "konto.flatex.de". The icon itself does appear, but the dropdown never comes up. Is there anything you can do here, or are you limited by the "autocomplete=off" set by the page itself?

Below you can find the collected website structure (sadly json attachments are not allowed here)
