.gif Attachment issue

When you upload a .gif in an .md file like this one, and place it under a `` format type, the .gif's playback doesn't restart when you open it multiple times.

Example:


Start by reproducing the behavior from the issue's .md example: open and close the block containing the linked GIF multiple times. Then inspect how this repository's generated documentation represents that Markdown and determine whether a repository change can address the playback behavior; done means the GIF restarts when the block is reopened.
