It seems that similar topics have been discussed in the past, but I couldn't find a solution. I would like to ask a question.

I am testing the following steps.

1. uninstall Marked2
   
2. install the latest version of Marked2 (Version 2.6.25 (1046))
   
3. do initial settings in "Prose Setting" of Quick Config
   
4. Open the following markdown file

The \\[ ... \\] format will display fine, but the $$ ... $$ format may or may not render. It seems to be related to the complexity of the formulas, but I don't know what is causing this.

OK

\[ \sum_{\mathbf{p} \in \mathcal{P}} \sum_{i \in \mathcal{I}(\mathbf{p})}\left(I_{i}\left(\pi_{i}(\mathbf{p})\right)-c(\mathbf{p})\right)^{2} . \]

---

NG

$$ \sum_{\mathbf{p} \in \mathcal{P}} \sum_{i \in \mathcal{I}(\mathbf{p})}\left(I_{i}\left(\pi_{i}(\mathbf{p})\right)-c(\mathbf{p})\right)^{2} . $$

Verify each component

OK

$$ \sum_{\mathbf{p} \in \mathcal{P}} $$

---

NG

$$ \sum_{\mathbf{p} \in \mathcal{P}} \sum_{i \in \mathcal{I}(\mathbf{p})} $$

---

OK

$$ \sum_{i \in \mathcal{I}(\mathbf{p})} $$

---

NG

$$ \left(I_{i}\left(\pi_{i}(\mathbf{p})\right)-c(\mathbf{p})\right)^{2} . $$

   It's happening on equations that have more than one underscore in them,
   I believe. This is being interpreted as Markdown italics, which then
   breaks the equation. I implemented the $$ syntax myself in Marked, so
   this is likely not a failure of MultiMarkdown. I'll have to dig into why
   these blocks are being processed as Markdown when they should be
   ignored.

   In the meantime, is it ok to use the \\[ syntax for the time being? I'll
   try to have a fix for this in the next update, but I'm rushing to get
   some Sonoma fixes out the door right now.

   Hi Brett,

   Thank you for your response. I see that the problem was regarding the parsing of underscores.

   I use both obsidian and marked2 and it is not practical to use the \\[ syntax. I will use obsidian only for a while and look forward to the fix of the problem and the release of a new version.
