This fix works for me and I hope you can pass it along to the developer as it’s very reliable.
There are 2 places I found where this needs to be implemented:
core/controllers/input.php Line 102
core/controllers/field_group.php Line 375
Change jQuery wrapper from:
(function($) {
...
})(jQuery);
To (note the $ moved):
var $ = jQuery.noConflict();
$(function() {
...
});
