"Language autocomplete (Tags style)" widget doesn't allow selection of languages with comma (i.e. Chinese, simplified)

Hi, in comment !4 🐛 "Language autocomplete (Tags style)" widget doesn't allow selection of languages with comma (i.e. Chinese, simplified) Active johnv described that the widget would work correctly if you wrap the language in quotes, then everything will work correctly. I added JavaScript, which automatically adds quotes when you select a language with autocomplete.
Before: Chinese, Simplified
After: "Chinese, Simplified"

Can confirm the changes in the MR fix the issue.

Thanks, committed.
I added some code when the field is a multi-value field.
