@proficad, We’re currently not able to reproduce the issue on our side.

Could you please share a few more details to help us investigate further?

• Does this happen with every sequence diagram or only a specific one?
• Could you share the Mermaid diagram code where this occurs?
• Does the browser tab fully freeze, or only the editor UI becomes unresponsive?
• Are there any errors shown in the browser console when the freeze happens?
• If possible, please share a screen recording of the issue.

You can upload screenshots or recordings by dragging them directly into the GitHub comment box.
