Use case or problem
When Auto pair Markdown syntax is toggled on, typing a single $ symbol is detected as a MathJax delimiter and auto-paired when typed. This interferes with the ability to enter dollar values, as attempting to enter $3.50 results in $3.50$.
Proposed solution
When the setting is toggled on, provide a new progressively disclosed option the user can enable that will cause Obsidian to ignore the $ when pairing.
Consequence
Users who toggle this behavior on will need to manually add $ symbols when entering MathJax formulas.
Users who do not enable this additional toggle would continue to experience the same behavior as they do currently.
Current workaround (optional)
Delete the offending $ suffix.
Every.
Single.
Time.
