How to globally disable the reduction of motion for existing animations?

[pioner92]

I would like to disable reduce motions for all animations.
I have many animation places and I need to add {reduceMotion:ReduceMotion.Never} to each place, this is not convenient

here is a fork with this flag disabled

This really should be a built-in feature

Agree. Can somebody share a patch here?

Hey!
This feature should be added soon. We already have an open PR which will add this functionality.
Hopefully this feature will land in soon.
I will close this discussion.
