Describe your issue

I am using a pattern where modals are opened and closed with v-if (for reasons why, see #2027).

<Dialog v-if="state === 1" open />
<Dialog v-if="state === 2" open />

One thing that I'm doing in several places is closing one modal while simultaneously opening another one (e.g. state++). As of v1.7.17, when trying to do that the second modal doesn't appear. See the linked reproduction for an example.

I can confirm that this behavior is not present in v1.7.16.

Hi, we still have the issue in the new versions of headlessUI v1.7.18, is the issue is planned to be fix ?

I am experiencing this issue as well. It is seemingly coming from #2700

I am experiencing the same issue as well, or at least it seems to have the same cause.

I am not using v-if, but when I am on a page where a Dialog can be opened (so the <div id="headlessui-portal-root">..</div> is set in the body)
-> then navigating (using vue-router 4.3.0) to the next page that also has a Dialog on the page, it gives an error when trying to open the Dialog because <div id="headlessui-portal-root">..</div> is not set in this next page.

After debugging I found out that it is definitely caused by version 1.7.17 and in #2700

Sorry about that! One of our changes cause a timing issue when switching dialogs in the same "tick". Fixed in @headlessui/vue v1.7.21

npm install @headlessui/vue@latest
