Check List

• I have already read Docs page & Troubleshooting page.
• I have already searched existing issues and they are not help to me.
• I examined error or warning messages and it's difficult to solve.
• I am using the latest version of Hexo. (run hexo version to check)
• My Node.js is matched the required version.

Expected behavior

The Post:

---
title: Hello World
date: 2021-10-09 21:50:25
refplus: true
---
<!-- more -->
Test {% ref self %}.
## Ref
{% references %}
[self] {% post_link hello-world hello-world %}
{% endreferences %}

All Markdown content between the ref and endreferences tags is rendered properly. And ## Ref is rendered as an h2 element.

Actual behavior

All Markdown content between the ref and endreferences tags is escaped, resulting in unrendered text.

How to reproduce?

sudo apt install npm
sudo npm install [email protected] -g
hexo init testenv
cd testenv
npm install hexo-reference-plus
cd source/_posts/
tee >hello-world.md  <<EOF
---
title: Hello World
date: 2021-10-09 21:50:25
refplus: true
---
<!-- more -->
Test {% ref self %}.
## Ref
{% references %}
[self] {% post_link hello-world hello-world %}
{% endreferences %}
EOF

Is the problem still there under Safe mode?

Others

I discovered this bug is caused by the escapeAllSwigTags function:

The ref and references tags share the same prefix. When escapeAllSwigTags uses endref to identify block-level tags, all content between {% ref xxx %} and {% endreferences %} is incorrectly escaped, resulting in unrendered Markdown.

This is clearly a bug:

1. The tag plugin functioned correctly with Hexo four years ago.
2. Plugins are restricted from sharing prefixes, and patterns like end${plugin_name} in text will also cause ambiguity.
