Password Regular Expression cause console-error in browsers

[samboman]

When entering anything in the password-fields that validates with a regular expression, the Chrome and Firefox consoles shows this faults. I have seen it on other sites using Azure B2C and local accounts.

Chrome:

Pattern attribute value ^((?=.*[a-z])(?=.*[A-Z])(?=.*\d)|(?=.*[a-z])(?=.*[A-Z])(?=.*[^A-Za-z0-9])|(?=.*[a-z])(?=.*\d)(?=.*[^A-Za-z0-9])|(?=.*[A-Z])(?=.*\d)(?=.*[^A-Za-z0-9]))([A-Za-z\d@#$%^&*\-_+=[\]{}|\\:',?/`~"();!]|\.(?!@)){8,16}$ is not a valid regular expression: Uncaught SyntaxError: Invalid regular expression: /^((?=.*[a-z])(?=.*[A-Z])(?=.*\d)|(?=.*[a-z])(?=.*[A-Z])(?=.*[^A-Za-z0-9])|(?=.*[a-z])(?=.*\d)(?=.*[^A-Za-z0-9])|(?=.*[A-Z])(?=.*\d)(?=.*[^A-Za-z0-9]))([A-Za-z\d@#$%^&*\-_+=[\]{}|\\:',?/`~"();!]|\.(?!@)){8,16}$/v: Invalid character in character class

Firefox:

Unable to check <input pattern=‘^((?=.*[a-z])(?=.*[A-Z])(?=.*\d)|(?=.*[a-z])(?=.*[A-Z])(?=.*[^A-Za-z0-9])|(?=.*[a-z])(?=.*\d)(?=.*[^A-Za-z0-9])|(?=.*[A-Z])(?=.*\d)(?=.*[^A-Za-z0-9]))([A-Za-z\d@#$%^&*\-_+=[\]{}|\\:',?/`~"();!]|\.(?!@)){8,16}$’> because ‘/^((?=.*[a-z])(?=.*[A-Z])(?=.*\d)|(?=.*[a-z])(?=.*[A-Z])(?=.*[^A-Za-z0-9])|(?=.*[a-z])(?=.*\d)(?=.*[^A-Za-z0-9])|(?=.*[A-Z])(?=.*\d)(?=.*[^A-Za-z0-9]))([A-Za-z\d@#$%^&*\-_+=[\]{}|\\:',?/`~"();!]|\.(?!@)){8,16}$/v’ is not a valid regexp: invalid character in class in regular expression

The pattern from /LocalAccounts/TrustFrameworkBase.xml are used.

Have anyone else seen this?
