(I hope this is the right place; https://github.com/ptwikis/ptwikis linked from https://tools.wmflabs.org/admin/tools offers no issue tracker. Also not sure who to subscribe to allow attention; I copied names from the page; please feel free to remove yourself.)

Steps to reproduce:

1. Go to https://ptwikis.toolforge.org/Filters
2. Enter language code and click "Go" button

Actual results:
On result page, see that <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> is in the source code.

Expected results:
Not loading content from a third-party server. Use https://tools-static.wmflabs.org/cdnjs/ajax/libs/jquery/1.11.1/jquery.min.js instead.
