Hello Alexey, I agree with you that it's a bug that invokes `-userDidEnterPassword:forPasswordView:` twice.

I think UIKit pass a block to WebKit, and WKPassword retain the block as property `userDidEnterPassword`. When the user double enter the password, it will crash.

I just upload a screen recording to reproduce the issue. Please check. Thanks.
