Disable iOS 12 strong password on a web app password form

Since the release of iOS 12, Apple's opinion of what a strong password is violates the back end rules my company defines as an acceptable strong password.

As a web developer, I cannot:

• Change how the back-end defines the password management rules (e.g. minimum characters, acceptable characters, etc.)
• Tell the customer to simply just disable or opt out of that iOS feature.

Quick background of my web app's password form:

• Written in Angular 4.
• Has the pattern attribute for input type password.
• Has the required attribute for input type password.
• Has the minlength attribute for input type password.

I was hoping for a quick win like a meta tag exclusive to this problem but could not find one. If you have an alternative JavaScript approach for handling this, please share.
