I am using webform-8.x-5.0 and created a telephone field with international phone numbers support. Before submitting the form if i enter some number like "+91fdfgdfg45646" it shows "Invalid phone number" (which i am not sure if it is a valid number or not). But when I submit the form it gets submitted. The issue is if it is invalid, the form should not have been submitted. Please suggest a solution. The form should not be submitted if it is invalid number.
Thanks in advance
