Use v-if as a workaround:

  <Foo v-if="frame === 'a'">
    <template #default="x">
      a
    </template>
  </Foo>
  <Foo v-if="frame === 'b'">
    <template #default="x">
      b
    </template>
  </Foo>
  <Foo v-if="frame === 'c'">
    <template #default="x">
      c
    </template>
  </Foo>

But it does have something wrong with v-else-if, I'm looking into it.

@JuniorTour Thanks, I'm aware of various workarounds (like using key), but I thought this behavior was odd.
