iOS 8 - iCloud Keychain with Multiple Login Accounts for a Site

I use iCloud Keychain to store multiple login accounts for a single website.

When using Safari on a Mac, the last login account I used for that site is prepopulated in yellow fields. If I want to change the login account, I clear the field with the login ID and I see a dropdown of all of the login accounts available for that site.

When using Safari on iOS 7, the last login account I used is prepopulated (just like with the Mac), but if I want to use a different login account, I need to enter enough characters in the login ID field for Safari to know which login account I want to use and then it autofills using that account.

Now, with iOS 8, all I get is the last login account I used. I can't figure out how to autofill any of my other login accounts for that site.

I'm pretty sure I'm doing something wrong, but I can't figure it out. Any suggestions would be appreciated.

Thanks.

Mike
