Issue Checklist

[x] I am using the latest version of NexT.
[x] I have read the relevant documents of Hexo and NexT.
[x] I have reviewed the latest Roadmap on GitHub and searched for current issues, which does not help me.

Expected behavior

I have modified /layout/_partials/widgets.njk file in order to hide reading-progress-bar in the home page

{%- if theme.reading_progress.enable %}
  {%- if not is_home() %}
  <div class="reading-progress-bar"></div>
  {%- endif %}
{%- endif %}

but the progress bar still displays on the home page
