Walkthrough

The changes made to the layout-sidebar.vue component involve a minor modification to the handleMouseleave function, specifically the removal of the border-t class from the VbenScrollbar component. This adjustment simplifies the scrollbar's styling by eliminating the top border, addressing a visual inconsistency noted in a linked issue while maintaining the component's overall functionality.

Objective	Addressed	Explanation
Suggest removal of top border in collapsed state (#4290)	✅

🐰 In the garden where I play,
The borders fade, they slip away.
With a hop and a bound, so light and free,
A cleaner view, just wait and see!
No more lines to block my view,
Just open space, and skies so blue! 🌼
