Steps to reproduce

if I click toggleVisible many times,

  1. the refDivSingle toggle between null and div
  2. the refCompSingle toggle between null and {}
  3. the refDivArr.length increase more and more <-- error here
  4. the refCompArr.length toggle between 3 and 0

if I use ref function, it don't get null

What is expected?

the refDivArr.length should toggle between 3 and 0, same as the refCompArr.length

What is actually happening?

the refDivArr.length increase more and more

a workaround:

<div v-for="(vv0, index0) in 3" :key="index0" ref="refDivArr">
+<div v-for="(vv0, index0) in 3" ref="refDivArr">
	<CompB ref="refCompArr"></CompB>
</div>
