Open https://www.blumenmaarsen.ch/mobile.php?c=order&id=1332&l=e in mobile Safari Fill in all fields in the recipients section. Everything else leave empty. Scroll down to the submit button. Click it. Because the form fields in the First delivery on section, there see Number of executions and periodicity, are mandatory (required="required" HTML5 attribute), Safari should firstly focus the empty field and secondly scroll to there as all the nonwebkit browsers do. Safari does not scroll to the required field.
