So you can use it works this way:

<el-popover trigger=\"hover\" placement=\"bottom\">
content....

<div slot=\"reference\">
<span>123</span>

<el-tag>123</el-tag>
</div>

</el-popover>

It doesnt work this way:

<el-popover trigger=\"hover\" placement=\"bottom\">
content....

<template v- slot:reference >
<span>123</span>

<el-tag>123</el-tag>
</template>

</el-popover>
