I have installed webform and client side validation extensions on my drupal project. The problem is in the webform's form element novalidate attribute is appearing, which cancels the client side validation.

Form HTML

In webform general settings I have unchecked the disable client side validation:

Webform General Settings

And finally in my form settings I have unchecked the disable client side validation:

Form Settings

Cleared cache but the novalidate attribute is still showing. Is there any way to remove this attribute from the form?
