Our script (that calls the sticky section) is called while page and content are fully loaded. Block height changes once you change the variation, so it’s impossible to revalidate the sticky section because it was done only once at the very beginning and can’t be done in other ways. Trigger that starts while you change the variation is – found_variation

Example of using in custom scripts $('.variations_form').on('found_variation', function() { console.log('variation found') } );
