I had an issue with one site where the maximum length on the "create new password" field was longer than the "maxlength" property on the input field for the login form. I couldn't figure out why I could use my password manager's autofill to login (since it ignored the maxlength), but couldn't type or paste my password in.

I think I've run into this issue multiple times but in the context of web-based login vs. logging in from an app. The problem went away when I used a shorter password.
