 * There are two forms on this page, both with radio lists, both broke somewhere
   between versions 3.15.0 and 3.15.2 (I have temporarily rolled back to 3.15.0).
 * The list Labels are text, and the list Values are email addresses, used to populate
   an ‘Email to chosen recipient’ action. I’ve done various tests with other Values,
   and the validation works with regular text but fails with email addresses, giving
   the message “Invalid selection.”
 * I see the Change Log includes 3.15.1 (24 August 2026) _Security Enhancements:_
   strengthen input validation for list field option imports, and it seems likely
   that this is the issue. But my forms are both manually created, rather than using
   import.
 * Is there some way of allowing email addresses in the form Values?
 * Thanks,
