Steps to reproduce

I've found some cases that shouldn't makes slot-component to update, but it does. Only case #1 works properly. It looks like a bug, because it affects at lot of cases when you want to pass slots through a component to a children with this technique.

Vue.component('W', {
  props: ['child'],
  template: `<component :is="child">
  <template v-for="(_, name) in $slots" v-slot:[name]="slotData"><slot :name="name" v-bind="slotData" /></template>
</component>`
})

What is expected?

no updates in children component

What is actually happening?

it does update
