Describe your issue

The Transition and TransitionChild component do not seems to work properly with Dialog (Modal) on the latest version of tailwind with React. I cannot see what's wrong with the code linked maybe something is missing ? I tried with only css as describe here without luck...
We also face some issue with Drawer components as well.

We use a standard slice with redux for controlling a "GlobalModal" but even with a local state, it does not work (see example above).

Does anyone has an idea ?

For info, does not work on Drawer as well. Example bellow is inspired from here

import React, { PropsWithChildren } from 'react'
import {
  Dialog,
  DialogBackdrop,
  DialogPanel,
  TransitionChild,
} from '@headlessui/react'
import { XMarkIcon } from '@heroicons/react/24/outline'
import classNames from 'classnames'

interface StandardDrawerProps extends PropsWithChildren {
  open?: boolean
  setOpen: (v: boolean) => void
  size?: 'sm' | 'lg' | 'full'
}

const StandardDrawer: React.FC<StandardDrawerProps> = ({
  open,
  setOpen,
  children,
  size = 'md',
}) => {
  return (
    <Dialog open={open} onClose={setOpen} className="relative z-10">
      <DialogBackdrop
        transition
        className="fixed inset-0 bg-gray-500/75 dark:bg-slate-900/75 transition-opacity duration-500 ease-in-out data-[closed]:opacity-0"
      />

      <div className="fixed inset-0 overflow-hidden">
        <div className="absolute inset-0 overflow-hidden">
          <div className="pointer-events-none fixed inset-y-0 right-0 flex max-w-full pl-10 sm:pl-16">
           {/*transition is useless, does not work*/}
            <DialogPanel
              transition
              className={classNames(
                'pointer-events-auto w-screen  transform transition duration-500 ease-in-out data-[closed]:translate-x-full sm:duration-700',
                {
                  'max-w-2xl': size === 'sm',
                  'max-w-2xl md:max-w-screen-md lg:max-w-screen-lg':
                    size === 'md',
                  'max-w-full': size === 'lg',
                }
              )}
            >
              <TransitionChild>
                <div className="absolute left-0 top-0 -ml-8 flex pr-2 pt-4 duration-500 ease-in-out data-[closed]:opacity-0 sm:-ml-10 sm:pr-4">
                  <button
                    type="button"
                    onClick={() => setOpen(false)}
                    className="relative rounded-md text-gray-300 hover:text-white focus:outline-none focus:ring-2 focus:ring-white"
                  >
                    <span className="absolute -inset-2.5" />
                    <span className="sr-only">Close panel</span>
                    <XMarkIcon aria-hidden="true" className="size-6" />
                  </button>
                </div>
              </TransitionChild>
              <div className="flex h-full flex-col overflow-y-scroll bg-white dark:bg-slate-900 shadow-xl">
                {children}
              </div>
            </DialogPanel>
          </div>
        </div>
      </div>
    </Dialog>
  )
}

export default StandardDrawer

I have cases where the modal doesn't show when explicitaly defining its open prop == true.

And sometimes it doen't close when the onClose prop is defined.
