Worse thing is, they look fine in preview.
for example the gif below looks fine in preview here, but prolly won't be animated when I post this.

The GIF in the CDN is fine, but the GIF that gets served on published posts has this form
<link>?auto=format,compress&gif-q=60&format=webm
for example, cdn.hashnode.com/res/hashnode/image/upload/v16386β¦
The "format" parameter seems to be messing this up,
as cdn.hashnode.com/res/hashnode/image/upload/v16386β¦ is animated.
Aspects of my articles kind of heavily rely on GIFs to convey information.
So it's a bummer they don't work anymore.
You can take a look at https://heaust.hashnode.dev/threejs-chapter-3
None of the GIFs in the article are animated :(

It took me a while to find out that this is actually an article you submitted as a bug report to hashnode. It was easier to find your article on google than the bug in the bugtracker, so I am linking it here if anyone else also wants to upvote it.
