Admin multi edit feature validation

The multiple edit feature is really a nice feature to have in the admin panel. But I don’t know how to perform server side validation with multiple edit feature. For example if I edit two users and remove the mandatory field e.g email field, it updates with blank email.

Is there a way to do a validation without loosing the multi edit feature or is it better to remove and update for edit/updates.

Note: The new design in the admin panel looks nice and more compact than the previous one. Thanks for the quick update.
