Describe your issue

After upgrading to vue 3.5.x from 3.4.38, there are no longer any transition animations on enter. Well, instead of saying "no animations" it seems to be related to the transition duration (from very random tests I've done).

In the codepen provided, sometimes, for no apparent reason, the dialog will show just fine, but 99% of the time, there are no enter transition (or an extremely brief one).

From what I can see, Vue has changed some behaviour with the native transition and teleport. Maybe it has something to do with it ? https://github.com/vuejs/core/blob/main/CHANGELOG.md

Only solution for now : downgrade to vue 3.4.x.

Hopefully you can find and fix this issue !

Also, the transition seems to be working fine with 1.7.16 plus vue 3.5.3. From 1.7.17 on, the enter transition breaks.

Also able to repro this on my end. Otherwise, 1.7.23 (latest at writing) + locking Vue to 3.4.38 does the trick as already stated.

There have been a number of transition-related changes in Vue core over the past month. Not sure where to start on this. https://github.com/vuejs/core/issues?q=transition+created%3A%3E%3D2024-08-01

GH diff link won't jump to file automatically, but was able to isolate this issue to changes made to packages/@headlessui-vue/src/components/portal/portal.ts in @headlessui/vue@v1.7.17 by pinning v1.7.17 and swapping out a built version of portal.ts@v1.7.16 locally.

I would guess that an { immediate: true } added to the watcher might fix it (??).

[mtzrmzia]

Is there any news on this issue?

[LePtiDev]

Same issue for me

[ixycej12]

I will add the style of class="${enterFrom}" to TransitionChild

[ixycej12]

If you don’t add it, there will be no entry animation.

[blackjak231]

I will add the style of class="${enterFrom}" to TransitionChild

This is actually working great in my case. It's clearly a temporary hack to get it working over a fix, but allows me to keep Vue up to date. Thanks for the tip @ixycej12

[marcos-c-vega]

I will add the style of class="${enterFrom}" to TransitionChild

Sorry, I'm not finding the correct way to add this, I tried the following but didn't work:

<TransitionChild
  as="template"
  class="${enterFrom}"
  enter="ease-in-out duration-500"
  enter-from="opacity-0"
  enter-to="opacity-100"
  leave="ease-in-out duration-500"
  leave-from="opacity-100"
  leave-to="opacity-0"
>

Do I have to include enterFrom somehow @ixycej12 @blackjak231 ?

[marcos-c-vega]

Ahhh I just found it was a reference to the class you are passing into enter-from attribute, so in my case enterFrom = opacity-0 so I placed it like:

<TransitionChild
  as="template"
  class="opacity-0"
  enter="ease-in-out duration-500"
  enter-from="opacity-0"
  enter-to="opacity-100"
  leave="ease-in-out duration-500"
  leave-from="opacity-100"
  leave-to="opacity-0"
>

Worked like a charm!

[ixycej12]

The current temporary solution, but there will be bugs.

[graphem]

Thanks! That worked for me too!

[HakwonChile]

Any fixed version?

[heartz66]

Most recent Vue fixed the issue for me.

the problem is still relevant
