• note to fixer: typo on this dialogue - 'Duplicaton of dialog' should spell 'Duplication'

@ashish315, Is it required for a11y purposes that duplication checks are made before clicking a new button? I think it's a reasonable scenario to come across a dialog that runs checks after the submit and then provides feedback to the customer.

For example, when creating a new username and password, often the customer isn't told until after they click submit that that username is already taken.

@corinagum I'm totally agree with your comment.
But for the accessibility point of view its beneficial if the error or duplication check at the time of typing. You can take reference from 'SharePoint' one of the Microsoft product.

@ashish315 That totally makes sense. Thanks for the feedback!
