Describe your issue

In v1.5.0 the afterLeave call of the Transition component was called after all Transition.Child components finished their leave animation. But now the Transition component calls this callback immediately and doesn't wait for animations of its child transition.

I rely on the afterLeave callback to know when it is safe to unmount a component with an exit animation.

Looks like they're actively working on it! #1585

[RobinMalfait]

This should be fixed by #1803, and will be available in the next release.

You can already try it using npm install @headlessui/react@insiders.

Here is an updated CodeSandbox with the latest insiders version: https://codesandbox.io/s/headlessui-transition-bug-afterleave-forked-ukknut?file=/src/App.tsx
