Worked on stabilizing code editor folding behavior in the godotengine/godot repository, focusing on interactions near region tags. Addressed a bug where folding would incorrectly trigger when comments were placed directly above or below region tags, which disrupted expected workflows. Introduced targeted checks in the C++ codebase to prevent folding in these scenarios, while ensuring that folding within multiline comments containing region tags remained functional. Applied code refactoring and unit testing to validate the solution and maintain code quality. This update improved the reliability of the editor’s folding feature, reducing accidental folds and enhancing the overall developer experience for region-tag workflows.
