Cognito Hosted UI triggers password validation for email input

I am using the Cognito Hosted UI to enable a user to sign up with an email and password. I have configured the pool to include password validation, but when using the host UI the password validation is triggered before the user ever focuses on the password field. I have tried to hide the validation with custom CSS but have been unsuccessful because AWS prevents adjacent CSS selectors. Upon inspecting the form, it clearly shows that the email field is calling the password validation function checkPasswordMatch() which to me is a bug. This does not happen on other fields such as family_name or given_name. Has anyone found a workaround for this?
