Subject: [PATCH] Animate avatar GIFs on-hover on public profiles (#10549)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Third time is the charm?

* Use full asset URL for data-static and data-original

̀image_tag` expands to the full asset URL, we have to do the same in `data` attributes so that it can work when assets and user data are stored on a different host
