What issue are you seeing?
In the code preview/pagination view, code lines that exceed the available width are wrapped onto additional lines instead of providing horizontal scrolling.
This makes long lines difficult to read and compare, especially for:
- long function signatures
- generated or minified code
- URLs and file paths
- JSON and other structured data
- diff-style code review
The current behavior significantly reduces readability and makes the code preview feel cramped.
What is the expected behavior?
The code preview should preserve the original line layout and provide horizontal scrolling or horizontal panning when a line exceeds the viewport width.
Ideally:
- horizontal scrolling should be available for long lines;
- automatic line wrapping should be disabled by default in code preview;
- an optional "Wrap lines" toggle could be provided for users who prefer wrapped text;
- the behavior should work consistently across code preview pages.
Why this matters
Code is often easier to understand when its original line structure is preserved. Wrapping long lines changes the visual structure of code and makes it harder to inspect signatures, aligned data, paths, URLs, and diffs.
A horizontal scrollbar, trackpad horizontal pan gesture, or an explicit line-wrapping toggle would provide a much better code-reading experience.
