 *
 * Given how much data can be captured in a child entry, Nested Forms provides a safety net by storing
 * submitted entry IDs in a cookie so that if the user accidently refreshes the page or closes the tab
 * their submitted entries can be restored.
 *
 * If you would prefer that Nested Form fields function like other fields where the data is not preserved,
 * use this snippet to disable Nested Forms sessions.
