Current problem
Twitch clips currently embed poorly, only showing the title, description, and thumbnail.
Proposed change
Include the video in the embed.
Additional information
Another popular chat platform embeds them in a playable state. I'm not sure what special handling the other chat platform uses, or if Twitch handles requests from the platform uniquely.
