Fieldgroup accordion does not open to first field of group
This is the solution I ended up using. I got it from I got it here: https://stackoverflow.com/questions/3621161/jquery-accordion-will-it-scroll-to-the-top-of-the-open-item.

I tested it at modules/contrib/field_group/field_group.js file at line 66. We then created a patch for it.

Not sure if this is the best solution, but it worked for us, so I thought I'd share the info.

activate: function( event, ui ) {
                    if(!$.isEmptyObject(ui.newHeader.offset())) {
                        $('html:not(:animated), body:not(:animated)').animate({ scrollTop: ui.newHeader.offset().top -150}, 'slow');
                    }
                }
