I've got some SPPB tabs set up - https://www.rnohprivatecare.com/patient-registration-forms-draft

On the iFrame tab, the bottom of the form has a signature panel, but we can't sign it.

The normal script is set-up in the other tabs and the field works as expected, but the client wants to use the iFrame so as they update the form, it updates in the website.

The iFrame version is also working in a text field below the tabs with the signature field working.

Do you know why?
