Hi @omsuneri,
Here's a quick demo screenshot showing .gif support working in the Media Block.
The .gif was successfully uploaded and appears on the stage as expected. Let me know if you'd like a video recording or exported project as well!

Hi again 👋
As a follow-up to the earlier screenshot, here's a more detailed view of the .gif being used across multiple media blocks.
It confirms consistent rendering and integration.
Let me know if a video or exported project would also be helpful!
