Summary

When viewing code examples in RTL mode (e.g., Arabic, Hebrew, Persian) on react.dev, the code overlay highlight does not appear correctly. Normally, when hovering over the code section, the corresponding preview area should be highlighted, but in RTL mode, the overlay is either misaligned or does not appear at all.
