 *
 * A small quality-of-life improvement that preserves the selected date when changing months via the Datepicker.
 * For example, if you selected October 16 and then used the Datepicker's "Month" dropdown to change the month to
 * December, the Datepicker would automatically select December 16.
 *
 * Instructions:
 *
 * 1. Install this snippet with our free Custom JavaScript plugin.
