autofill MacOS / Chrome Autofill not working for Synology NAS Photostation app

[rantanplan 0]

Hi

Seems to be that the autofill function is not working for Synology Photostation login.

URL:
http://miracuruzrh.synology.me/photo

I tried many different settings with password and username field type and url. Seems to be that the password and username is filled in the background. When then the login button on the page is clicked then the fields are filled out.

But when opening the login overlay and then let en pass trigger the autofill then the fields aren't filled out.

Any idea how to correct this?
