How to solve this array comparison problem?

Question

JavaScript

Given: a multiselect customized by chosen and several divs each with their own data-prop set.
It is necessary: ​​to highlight the divs with the corresponding data-props when the select is on change
The task was partially solved like this https://jsfiddle.net/u04azze1/ - on the first selection, the corresponding divs are highlighted
But on the second - the program does not work correctly, comparing the arrays of selected options and blocks with data props does not work.
Where did I go wrong?

Answer 1

Main build: https://jsfiddle.net/u04azze1/1/
Corrected the coloring when the tags field is empty and speeded up the check with break: https://jsfiddle.net/u04azze1/4/
PS: checked: works with jquery 1.12.4 ( which is under IE8)
