Description
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?
9.7.1
What's Wrong?
When using useTransition, if you pass in a boolean as the first argument and a function as the second argument, the transitions do not run as expected.
This syntax use to work in previous versions up until version 9.5.2, where it's suddenly stopped working.
To Reproduce
Code sandbox which demonstrates the issue https://codesandbox.io/s/little-voice-5hl8w6?file=/src/App.tsx
Expected Behaviour
If this syntax is not valid, I would expect to see some Typescript errors.
If it is valid syntax, I expect the transitions to run as expected.

Research direction
Start with the linked CodeSandbox reproduction, especially src/App.tsx, and inspect the @react-spring/web useTransition call that passes a boolean followed by a function config. Compare its behavior between version 9.5.2 and 9.7.1. Done means the documented syntax either animates as expected or produces an appropriate TypeScript error.
