🐛 data-tags: true problem in ModelSelect2TagWidget. automate seperate words. not working #274

Bug Description

Due to the nature of Hangul, it consists of consonants and vowels.
If you try to add a tag as '비상금', it will change to '비상ㄱㅡㅁ' or '빗ㅏㅇ금' or '비ㅅㅏㄱㅡㅁ', etc.
For some reason, I looked it up and found that data-tags is true when using ModelSelect2TagWidget, but this phenomenon only occurs in this case.
In ModelSelect2MultipleWidget, it is normally displayed as '비상금'.
I found the cause and how to solve it, but I'm not sure how to solve it. Please solve it.
Adding data-ajax--delay alleviates this slightly.

Steps to Reproduce

you try to add a tag as '비상금', it will change to '빗ㅏㅇ금' or '비ㅅㅏㄱㅡㅁ'
