Long first/last names without spaces break mobile view layout

[sukhendu2002]

When a user has a long first name or last name without spaces, the layout in the mobile view of the WordPress site breaks.

Steps to Reproduce:

• Navigate to Users > Add New in WordPress admin
• Create a new user with a very long first name or last name without spaces
• View in mobile layout

Fixed the issue where long first/last names without spaces broke the mobile layout by overflowing their containers.
