[csswg-drafts] [scroll-animations] TAG feedback: interaction with prefers reduced motion (#5321)

majido has just created a new issue for https://github.com/w3c/csswg-drafts:

== [scroll-animations] TAG feedback: interaction with prefers reduced motion ==
Here is a question/feedback from TAG. The original is [here](https://github.com/w3ctag/design-reviews/issues/521#issuecomment-657984261) but I am creating this issue to track this in CSSWG as well.

> Given that one of the use cases this API is explicitly designed to enable is parallax scroll effects, which is a known trigger for vestibular disorders, it might be worth considering how this feature integrates with prefers-reduced-motion.

> For example, should animations expressed using this API be disabled by default if `prefers-reduced-motion` would match? And if so, could we design a way to allow animations to express that they are safe to be shown for users who prefer reduced motion?

> I think it might even be worth opening a broader discussion on what the default behaviour for prefers-reduced-motion should be for all web APIs which allow animation, but I think the question is especially critical for this API given it's more likely than average to cause harm to users.
