Let's say I have login A with the website set to https://example.com and login B with the websites set to http://192.0.2.42 and https://foo.example.com. In this case, filling on https://foo.example.com will simply sort A before B alphabetically. However, if I swap the two URLs for login B and put https://foo.example.com first, the FQDN match is correctly sorted first.
This is not a huge concern in my case as swapping the URLs resolves the issue but it may become a problem in more complex cases.
