Specifying a key on QTd other than column.name results in nothing beeing rendered

What happened?

I have written a custom wrapper around the QTable that overwrites the body slot and allows a user to specify a column-component.

I have keyed both if-paths like so:

<component
  v-if="col.component"
  :is="col.component"
  :key="col.name + '_c'"
  v-bind="{ ...props, col, value: col.value }"
  v-on="_listeners"
/>
<q-td v-else :key="col.name + '_p'" :auto-width="col.autoWidth" :props="props">
  {{ col.value }}
</q-td>

This resulted in nothing being rendered for columns using no custom component.

What did you expect to happen?

I would have expected that the QTd would render normally.

Additional context

I would be happy if this would be mentioned within the docs, in my case the workaround was trivial once the problem was identified.

It has nothing to do with the keys You are setting :props="props" - check what you want to do there
