:host="host"

What does "host" do, I've found that without it the iframe height doesn't adapt?

What does "host" do

It can be used to use a different giscus server, e.g. if you run a self-hosted instance.

I've found that without it the iframe height doesn't adapt?

What version of the component are you using? That issue should've been fixed recently.

I use the v2.2.6 version of @giscus/vue.

I must add host="https://giscus.app" to fix the problem of iframe height.

<template>
  <Giscus
    id="comments"
    repo="laoergege/laoergege-blog"
    repoId="MDEwOlJlcG9zaXRvcnkxMjM4OTQ4MDE="
    categoryId="DIC_kwDOB2J8Ec4CTiA5"
    mapping="specific"
    :term="discussionID"
    strict="0"
    reactions-enabled="1"
    emit-metadata="0"
    input-position="top"
    :theme="compTheme"
    lang="zh-CN"
    loading="lazy"
    host="https://giscus.app"
  />
</template>

Yeah, this confuses me a lot. But the host do fixed the height issue.

Finally found the cause, apparently Vue sets the host to an empty string if you don't specify it, but only on subsequent renders (not the first one).

Should be fixed in v2.3.0, please update and confirm. Thanks!
