[bug]: SpringValue.set doesn't schedule update to interpolation on first render #2374

Description

@LoganDark

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?

so in our app

Image

the top console log is from inside the to callback and the bottom console log is from the function that called entryValue.set in useResizeObserverAsSpringValue (see the codesandbox repro thing for gdfjhbgskj)

basically the call to entryValue.set seems to do nothing the first time it happens and doesn't properly schedule the interpolation to update

the next time the value is set and all other times works fine, just not the first time

To Reproduce

I guess call a springvalue.set inside a useEffect when the springvalue is part of an interpolation that already got passed to an animated.div, or something like that

repro has it and reproes consistently

Expected Behaviour

the call to springvalue.set should update the interpolation
