Version

3.0.11

Reproduction link

https://jsfiddle.net/Lrnebjuv/24/

Steps to reproduce

• Click button "Click me" multiple times

What is expected?

Text below button should show 1, 2, 3 in a loop

What is actually happening?

Text shows 1, 1, 3 instead

Also happens without .children.default() using <slot></slot> instead in this variant https://jsfiddle.net/Lrnebjuv/25/

Original context is a tab component: https://github.com/rashfael/buntpapier/issues/22 https://github.com/rashfael/buntpapier/blob/vue3/src/tabs.js

as a workaround add key to p:

    <Bar>
      <p key="1" v-if="true">
        1
      </p>
    </Bar>
    <Bar>
      <p key="2" v-if="true">
        2
      </p>
    </Bar>

201060717d4498b4b7933bf8a8513866ab9347e4 is a partial fix which does not fix the <slot/> variant
