Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
Cursor iteratively writes out its plan. This is nice in a way: I can read it bit by bit as it’s coming through. But since installing the Mermaid plugin, this iterative rendering of the generated .md plan is continually rendering, removing, and re-rendering the Mermaid diagram, making it impossible to read as it’s being generated (and greatly slowing down the rendering as well). I need to sit and patiently wait for the plan to complete before I can look at it at all.
Steps to Reproduce
- Install Mermaid markdown rendering plugin
- Ask Cursor to generate any kind of plan that includes Mermaid diagrams
Expected Behavior
The Mermaid diagram should render once, then stay. That way I can look at the diagram and read the contents of the document as they come through.
