Steps to reproduce

Have something similar to this:

<slot v-for="item of [1,2,3]" :ref="setRef1" :key="index"/>
<div v-for="item of [1,2,3]" :ref="setRef2" :key="index"/>

function setRef1(element) {
 console.log(element) /// always undefined
}

function setRef2(element) {
 console.log(element) /// works as expected
}

What is expected?

Refs should be set

What is actually happening?

The first param passed to the setRef function is always undefined
