Uncaught TypeError: Cannot read property ‘top’ of undefined at (index)

Plugin: 1.0
Gravity Forms: 2.4.12 (or latest 2.5.6)
WordPress: 5.7.2

Getting a “Uncaught TypeError: Cannot read property ‘top’ of undefined at (index):142” error when submitting a form. Tested a form on a brand new page on a clean Twenty Twenty-One theme with this plugin and Gravity Forms plugin.

Error points back to Gravity Forms JS, conflict with the following function:

setTimeout(function() {
  jQuery('#gform_wrapper_1832283327').replaceWith(confirmation_content);
  jQuery(document).scrollTop(jQuery('#gf_1832283327').offset().top - mt);
  jQuery(document).trigger('gform_confirmation_loaded', [1832283327]);
  window['gf_submitting_1832283327'] = false;
}, 50);
