Issue w/WooCommerce Authorize.Net CIM Gateway v2.5.1

When Authorize.net CIM Gateway plugin is set to test mode, everything works as intended. However, once the plugin is changed to Production the “maxlength” attribute of the credit card field and CVV field are set to 0. This problem is fixed when WooCommerce Checkout Field Editor (Manager) Pro is deactivated.

I was able to create a workaround by removing
esc_attr( $args['placeholder'] )
around line 970 of class-wcfe-checkout-field-editor-frontend.php. Obviously this is not desirable but it works for now.
