it's work only if:
maxItems: 1,
And it cause some problem
But when maxItems > 1, then dropdown is never close when i click on focused selectize-input.
the problem is that value beacame = ''
I use this selectize/selectize.js#340 (comment) to solve situation when user type wrong text for autocomplete, and then click out of the input - the value is restore to previos.
