setCustomValidity is not a Function

[msawatzky75]

HTMLInputElement.prototype.setCustomValidity is not a function.

right now, i am able to get around the issue by mocking it:

import { vi } from "vitest";
window.HTMLInputElement.prototype.setCustomValidity = vi.fn();

Thanks for reporting @msawatzky75! 🙂

I have added support for HTMLInputElement.setCustomValidity(), HTMLInputElement.reportValidity() and HTMLInputElement.validationMessage now.
