Users can click "Add Another" to clone groups of fields, simulating CRM forms and job applications
Technique: Users can click "Add Another" to clone groups of fields (e.g., multiple phone numbers, addresses, team members). Each group is created by cloning a <template>. Users can also remove groups with an "X" button.
Why it matters: Very common in CRM forms, job applications, surveys, and order forms. Gravity Forms, Formidable, and many custom forms use this. Each "add" creates new DOM elements with indexed names (e.g., phone[0], phone[1]).
Expected result (STRESS TEST): Adding/removing field groups changes the DOM structure. If the SDK fingerprints before the user adds more, the cache will have the original hash. If re-fingerprinted, the new fields would change the hash. Tests the boundary of what the cache can handle.
