Worked on the ueberdosis/tiptap repository to address a critical bug affecting editor rendering in client-side Next.js applications. Focused on improving the immediatelyRender option, the solution ensured that explicit user values were respected rather than being overridden by default logic, which previously caused issues when isNext was true. The approach maintained server-side rendering safety by continuing to default immediatelyRender to false, preventing crashes, while enhancing reliability and predictability for client-side usage. Utilized TypeScript, React, and Next.js to implement the fix, resulting in a more robust editor experience and reducing production incidents related to configuration inconsistencies in Next.js environments.
