[] When the flag is enabled and I view a page fresh from cache the list of references is not there and instead I see a link to "See references for this page" that points to a Special:References page.
[] Ship references in JavaScript config for time being (the references JavaScript blob will be smaller than the HTML equivalent
[] The ReferenceDrawer should load reference data from the blob when the HTML is not present
[] Any links inside a sup tag with class reference should be rewrite to be prefixed with a local URL for Special:References e.g.
```
<sup id="cite_ref-18" class="reference"><a href="#cite_note-18"><span>[</span>18<span>]</span></a></sup>
```
becomes
```
<sup id="cite_ref-18" class="reference"><a href="/wiki/index.php/Special:References#cite_note-18"><span>[</span>18<span>]</span></a></sup>
```
[] Feature flag should be disabled by default
[] Enable the change on the beta cluster in the stable channel.
[] Observe impact on loading time in https://grafana.wikimedia.org/dashboard/db/mobile-2g and note them in the card.
Open questions to be decided later:
* Do we ship the references JSON blob via the API instead
** If we do how does this impact the references drawer?
** When do we load references? When a reference is clicked?
Developer notes:
* Feel free to use the MobileFormatter for this one.
