Description

Does this issue occur when all extensions are disabled?: Yes

  • VS Code Version: 1.85.1
  • OS Version: Windows 11

In markdown file, multiline math expressions like the following are valid and supported by the official markdown preview feature. But the inside of the dollar signs is not recognized as math/latex context unless the beginning dollar sign is at the start of the line. I checked the context by "Inspect Editor Tokens and Scopes".

aaa $\begin{pmatrix}
1 & 2 \\
3 & 4 \\
\end{pmatrix}$ bbb

I have a lot of latex snippets for writing math expressions in markdown, but they are not suggested in such expressions for this issue.

btw, I have a setting "markdown.preview.breaks": true. When this is true, I think the only way to write an inline multiline math expression is like this.

Contributor guide

Research direction
Inspect the VS Code markdown TextMate grammar for math context. Look at how inline math spans are tokenized across lines. Use the 'Inspect Editor Tokens and Scopes' tool to identify where tokenization breaks. Focus on the opening $ pattern and line continuation rules.
