1. Click on [Create an account] - Sign up form opens
2. Fill all fields with valid data, but pessword fields should be different. E.g. Password - 123456789; Repest password - 112345678
3. Delete number 1 from the field "Repeat password"
4. Delete number 9 from the field "Password"
5. Look under the field "Repeat password"

Expected result: If the passwords are match, informational message under the field "Repeat password" disappears.

Actual result: If corrections are first made to the field "Repeat password", informational message "Password mismatch" doesn't disappear.
