if every div use v-if,then there will be no description problem. If for each 'Sup' component add :value="value", scopedSlot content will update normally

You need to add unique keys to if branches if they are using the same kind of element.

thanks, Adding a unique key can also solve the problem. I found another issue #12244,similar to this one, it fixed #12223 ,but still can't update with the above demo.So I think it's a vue problem

The current result is if i use v-else-if or v-else and children have the same component, i need to add a unique key to each component

Use v-if as a workaround:
