Upgrading from 4.0.5 to 4.0.7 and ran into an issue where this code no longer works:

$(document).ready(function() {
  $("#select1").select2().select2("focus");
  $("select").on("select2:close", function (e) {
	 $("#checkbox1").focus();
	});
});

The goal is to auto-select the select2 on page load, then after the select2 is closed, focus on the next element. With 4.0.5 it works, with 4.0.7, the select2 element remains focused.

Example w/4.0.5 which works:
