In multi-select, selections do not appear in the order in which they were selected

...All the tags appended to the end show up in an arbitrary place in the Select2 box. There seems to be no rhyme or reason where they will appear, neither alphabetical nor sorting by list matching. It just randomly sorts each time. This seems to be the reverse of issue #2283, so I'm not sure how to actually force the tags to append.
