All versions of django-smart-selects prior to version 1.2.8 are vulnerable to an XSS attack as detailed in issue 171. As a result, all previous versions have been removed from PyPI to prevent users from installing insecure versions. All users are urged to upgrade as soon as possible.

Checklist

^{Put an x in the bracket when you have completed each task, like this: [x]}

• [X] This issue is not about installing previous versions of django-smart-selects older than 1.2.8. I understand that previous versions are insecure and will not receive any support whatsoever.
• [X] I have verified that that issue exists against the master branch of django-smart-selects.
• [X] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [X] I have debugged the issue to the smart_selects app.
• [X] I have reduced the issue to the simplest possible case.
• [ ] I have included all relevant sections of models.py, forms.py, and views.py with problems.
• [ ] I have used GitHub Flavored Markdown to style all of my posted code.

Steps to reproduce

1. Tried using Admin TabularInline on my models using smart-selects
2. The default number of rows kept at 1 ("extra = 1")
3. The inline is working normally (with the filled / selected dependent field value) and also is able to save data as expected.

Actual behavior

1. Adding a new row fails to show the dependent field value on selection as experienced in the first row (correctly and as expected).
2. If the value of "extra" is changed (say, to 2 or 3 or such) all the rows produced in the inline demonstrates the smart-selects behavior correctly. While adding a new row fails.

Expected behavior

1. The dependent field should show the value corresponding to the chained field value selected (as normally expected and demonstrated)

Using:

1. Python: 3.6
2. Django: 2.0.6
3. smart-selects: 1.5.4
4. js-unlinting-fixes installed

P.S. Found a similar issue on Git but that was about django-ajax-selects.
