Animated images and emoji

In your a11y settings would it be possible to decouple "allow animated images and emoji" into 2 separate settings like "allow animated images" and "allow animated emoji"?

Usually I'm fine with animated images but I have a real issue with animated emoji. In particular the popular party parrot emoji instantly does something weird to my eyes and makes feel sea sick. It's literally like a feeling of nausea in my eyes and brain. I have to immediately look away if I see that. I was really happy when I discovered Slack's a11y settings! The only downside is that I miss out on animated gifs.

Have you had any other people report issues with emoji like the party parrot ones? I feel like those in particular are potential seizure risks because they quickly flash and rotate. Google "WCAG seizures" for context.

I personally also have a similar adverse yet less extreme reaction to some horizontal slide transitions common on many websites especia
