Multiple multiselect blur fails to close dropdown

Tested with select2 3.2 and the latest from master.

Moving between multiple multi-selects on the same page does not close the dropdown on the initially-focused multi-select. Example jsfiddle here:

Clicking on the first multiselect and then the single select, the dropdown closes properly on blur. Clicking the first multiselect and then the second multiselect, both remain open.
