Whenever, I hit the "reset" button on the signature pad element to clear the signature , the webform wizard sends me back to the previous page.

Steps to reproduce:
1 - Enable the webform examples module
2 - Edit the multi step example wizard form (/form/example-wizard)
3 - Add a "signature pad" element to the 2nd or last page.
4 - Test the form and click on "reset" on the signature pad element to clear the signature

Result:
The webform brings you back to the previous page and never clears the signature.

I think this started happening when I updated the webform to the latest version on drupal 8

I am using:
Webform 8.x-5.0-beta14
Drupal version: 8.3.4
