Why I have additional `$$` characters before and after rendered LaTex equations?

[LYK-love]

Issue Checklist

• I am using NexT version 8.0 or later.
• I have already read the Troubleshooting page of Hexo and Troubleshooting page of NexT.
• I have already searched for current issues, which does not help me.

Expected behavior

For markdown codes like

The gradient-ascent algorithm maximizing $J(\theta)$ is
$$
\begin{aligned}
\theta_{t+1} 

&= \theta_t+\alpha \color{orange}{\nabla_\theta J (\theta_t )} \\
&= \theta_t+\alpha \color{orange}{\mathbb{E}_{S \sim \eta, A \sim \pi(S, \theta)} [\nabla_{\theta} \ln \pi (A \mid S, \theta_t) q_{\pi}(S, A) ]}
\end{aligned}
$$



The stochastic gradient-ascent algorithm is
$$
\theta_{t+1}=\theta_t+\alpha \color{pink}{\nabla_\theta \ln \pi\left(a_t \mid s_t, \theta_t\right) q_\pi\left(s_t, a_t\right)}
$$
We can see "actor" and "critic" from this algorithm

It is expected to render two LaTex equation blokcks,

NOTE: This image is from my markdown editor Typora, which renders perfectly, instead of from a deployed site with Hexo Next.

Actual behavior

• Links to demo site with this issue: https://66859f4844996f0008f145ad--lyk-love.netlify.app/2024/06/24/actor-critic-methods/
• Screenshots:

However, in the deployed site (either locally or on the Internet) I have these two additional $$s around my blocks sometimes. This means that my render engine, hexo-renderer-pandoc, may work incorrectly?

Steps to reproduce the behavior

The gradient-ascent algorithm maximizing $J(\theta)$ is
$$
\begin{aligned}
\theta_{t+1} 

&= \theta_t+\alpha \color{orange}{\nabla_\theta J (\theta_t )} \\
&= \theta_t+\alpha \color{orange}{\mathbb{E}_{S \sim \eta, A \sim \pi(S, \theta)} [\nabla_{\theta} \ln \pi (A \mid S, \theta_t) q_{\pi}(S, A) ]}
\end{aligned}
$$



The stochastic gradient-ascent algorithm is
$$
\theta_{t+1}=\theta_t+\alpha \color{pink}{\nabla_\theta \ln \pi\left(a_t \mid s_t, \theta_t\right) q_\pi\left(s_t, a_t\right)}
$$

@LYK-love Could you share which math engine are you using? It should be in the something like this under _config.next.yml:

math:
  every_page: false
  mathjax:
    enable: true
    tags: none
  katex:
    enable: false
    copy_tex: false

Also please share your markdown key in _config.yml, like this:

markdown:
  render:
    breaks: false
  plugins:

Sure, my math renderer is hexo-renderer-pandoc and I use mathjax.

math:
  # Default (false) will load mathjax / katex script on demand.
  # That is it only render those page which has `mathjax: true` in front-matter.
  # If you set it to true, it will load mathjax / katex script EVERY PAGE.
  every_page: false

  mathjax:
    enable: true
    # Available values: none | ams | all
    tags: ams

  katex:
    enable: false
    # See: https://github.com/KaTeX/KaTeX/tree/master/contrib/copy-tex
    copy_tex: false

I don't have markdown key in _config.yml. I think it's for hexo-renderer-markdown-it, while I use hexo-renderer-pandoc instead.
