The issue is that underscores inside math formulas ($...$) are incorrectly rendered as italic in markdown. The fix likely involves modifying the markdown language grammar (e.g., markdown.tmLanguage.json or monarch tokenizer rules) to disable italic inside math environments. Look at the existing grammar files in src/language/markdown/, particularly the tokenizer rules for ` ` and `*`. Investigate how math formulas are tokenized and ensure that underscores inside $...$ are not treated as emphasis markers. Test with the provided example after making changes.
