The worst offender I have seen in the wild is treasurydirect.gov. The password must be click in on an online keyboard, and they do not allow password managers to enter the passwords. Screenshot here: https://en.m.wikipedia.org/wiki/TreasuryDirect
Citibank is bad, too. It uses some kind of JS trick to replace usernames and passwords with asterisks, and you end up with all kinds of invalid information stored in your password manager.
Have they ever heard of input type="password"?
