Made some tests.
The issue is not vite. It works fine with [email protected] (latest as of the time of this writing)
The problem is with [email protected] and higher

I did a test and it works again after I removed the tag="transition-group"
Tested under "vue": "^3.2.33", "vite": "^2.9.5"

In the temporary solution of vue3.2.33 version, remove the tag="transition-group" attribute, you can run the code normally

remove the tag="transition-group" attribute, it's ok

[JokerMartini]

If you remove the transition-group attribute, then you are forced to use a vertical layout of draggable. What does transition group do under the hood that i could mimic without adding the attribute?

[JokerMartini]

Code like this

<draggable
      v-model="appItems"
      tag="transition-group"
      v-bind="dragOptions"
      item-key="uid"
    >
      <template #item="{ element }">
        <AppItemCard :item="element" :key="element.uid" />
      </template>
    </draggable>

Which previously worked, no longer works with the latest version of vue.

[JokerMartini]

if you downgrade your vue to vue 3.2.30 it will work

if you downgrade your vue to vue 3.2.30 it will work

Have you solved it?

it's none of business with vite, it's problem about vue's component transition-group ,it lost el dom property
