Reproduction link
https://github.com/guanzo/codesandbox-nuxt
Steps to reproduce
$ git clone https://github.com/guanzo/codesandbox-nuxt nuxtbug
$ cd nuxtbug
$ npm i
$ npm run generate
$ npx http-server dist
Open the webpage and dev tools, go to the Elements tab, expand the <head> node
Note the position of the element
<script data-n-head="true" src="https://arc.io/widget.js?MURGrEjPmB6gVvzyvpbDut" async=""></script>
Note the element <div id="arc-widget"></div> at the bottom of <body>. This element is created when the arc.io/widget.js script is loaded.
Click the "test" link
The <head> is updated and the script has been appended to the bottom of <head>, causing it to execute again, and now there are 2 #arc-widget elements.
What is expected ?
A script is loaded once across all navigations.
What is actually happening?
A script is loaded twice across all navigations.
Additional comments?
Related to nuxt/nuxt#3396.
This only occurs when each nuxt page has its own title. When nuxt updates the page title on navigation, the script is reappended. The hid attribute on the script tag doesn't fix it.
