Running the Javascript tests requires an internet connection to
https://cdnjs.cloudflare.com .

This makes the tests dependent on an extra third party, provides that
third party with the IP address of developers and test runners, and
prevents developers from running the tests without a connection to
Cloudflare.

The relevant line is in `js_tests/tests.html`:

<script
src='https://cdnjs.cloudflare.com/ajax/libs/ol3/4.6.5/ol.js'></script>

== How to reproduce

1. Install the dependencies using npm

git clone https://github.com/django/django.git
cd django/
npm install

2. Serve the page via a web server and open in in a browser

python3 -m http.server --bind 127.0.0.1

Open http://localhost:8000 with the network inspector open.
