payload duplication without template

[sashafirsov]

<cem-badge text="999+">
        <cem-icon image="🛒" vertical="middle"></cem-icon>
</cem-badge>

While with template payload rendered only once

<cem-badge text="999+">
    <template>
        <cem-icon image="🛒" vertical="middle"></cem-icon>
    </template>
</cem-badge>
