Thanks for the fix @Sbragul26,

I reviewed the issue and verified that the reported behaviour was legitimate. The sidebar content was getting clipped because of overflow: hidden, which made the lower sidebar items difficult or impossible to access properly.

I also checked the updated behavior in the preview. In full-screen view, the sidebar works well and the content is accessible. In windowed/resized view, the last sidebar item still appears only near the end of the page scroll, but the important part is that it is no longer clipped or unreachable.

Since this PR fixes the main usability issue and keeps the change minimal and focused, it looks good to me.
