[bug]: springs won't work using view-transition web API

[JoaoTeixeira20]

Which react-spring target are you using?

• @react-spring/web
• @react-spring/three
• @react-spring/native
• @react-spring/konva
• @react-spring/zdog

What version of react-spring are you using?

10.0.1

What's Wrong?

More details on the setup:

next.js: 15.3.4
react: 19.1.0
next-view-transitions: 0.3.4

NOTE: mentioning that i downgraded react and react-spring to ^18 and ^9 respectively in order to check compability issues but they have the same behaviour

Seems any component rendered when a view-transition starts, makes the animation freeze when it's supposed to play, this is a very tricky setup since there are multiple libraries used to reproduce this error, but under the hood, I think this is related to the native startViewTransition call.

Wrapping the router call under a useTransition react hook to track the loading and render the component containing the animation freezes.

Also, seems any spring playing in a loop, the moment the transition starts, the animation freezes.

I don't know if this is a silly mistake i'm making for not properly use requestAnimationFrame or flushSync from react

To Reproduce

you can test this repo:
https://github.com/JoaoTeixeira20/next-transitions-demo/tree/with-react-spring-in-transition

Also a demo with this occuring:

Expected Behaviour

Any animation should start/not stop during a view-transition API call

Update:
Seems react-spring isn't the issue, tested other animation library that animates properties with javascript and still froze, i'm currently investigating more the native view transition API along with how the transition library interacts with react with next.js on page transitions.

This issue can be closed.
