Render warning when using v-if v-else in VueJS - NuxtJS (SSR)?

Question

Vue.js

I use a simple component to display a logo with or without a link, depending on whether we are on the main page or not

<template lang="pug">
  nuxt-link(v-if="!isMain"  to="/")
    os-svg(name="logo")
  os-svg(v-else name="logo")
</template>

when starting a local server and navigating through the pages, everything is fine, but when opening the /about page directly from the address bar or when reloading the page, it throws a warning
vue.runtime.esm.js:430 [Vue warn]: The client-side rendered virtual DOM tree is not matching server-rendered content. This is likely caused by incorrect HTML markup, for example nesting block-level elements inside , or missing . Bailing hydration and performing full client-side render.
In os-svg lies

<template lang="pug">
  svg.svg(:width="width", :height="height")
    use(:xlink:href="'#'+name")
</template>

That you can't use v-if v-else in NUXT (i.e. SRR) at all?
