== Background
The `mfLazyLoadReferences` cookie was added in {10ea53879ec15e5fd5ce50ef6a9fb54191437e0d} ({T129693}) so that the lazily loaded references feature could be enabled for a fraction of the overall population of users.
As the lazily loaded images feature is now deployed to users who have opted into the mobile site's beta mode, this cookie is now redundant.
