Problem with Submit button if Stripe PP is default

Hello,

I am running with webform-civicrm 7.x-5.0, webform 7.x-4.22, CiviCRM 5.21.1

I have a webform which collects a user's details and allows them to pay for a Membership in our organisation. On the payment page it offers the Pay Later option and Credit card using the Stripe Payment Processor.

• Selecting Stripe works OK.
• If Stripe is set to be the default option, but one selects Pay later and then clicks Submit, the webform returns to the previous page without doing the Submit action, exactly as if the Previous Page button were clicked.
• If Pay Later is the default Option then clicking Submit works correctly.
• If Pay Later is the default, but one selects Stripe then Pay Later again, it goes back to the previous page as above.
• If there is no default then selecting Pay Later and Submit is fine.
• If I set up the Dummy Card Processor and Pay Later in the same way it works OK.

Thank You.
Tony
