I tried these solutions with the select2 version 3.4.8 and found that when you do blur, the select2 triggers first select2-close then select2-focus and then select2-blur, so at the end we end up reopening forever the select2.

Then, my solution is this one:

$('#elemId').on('select2-focus', function(){
    var select2 = $(this).data('select2');
    if( $(this).data('select2-closed') ){
        $(this).data('select2-closed', false)
        return
    }
    if (!select2.opened()) {
        select2.open()
    }
}).on('select2-close', function(){
    $(this).data('select2-closed', true)
})
