Depiction of the problem.

SUMMARY
When Dolphin's panels' heights are reduced to their minimum, if multiple buttons at the end of each scroll bar have been enabled, these overlap. Additionally, the scrollbar toggle disappears.

STEPS TO REPRODUCE
Per https://discuss.kde.org/t/can-the-scrollbar-background-always-be-shown-like-in-windows/12296/33?u=rokejulianlockhart:
1.  Invoke “kcmshell6 kcm_style”.
2.  Edit Breeze.
3.  Select “Scrollbars”.
4.  Select “Two buttons” for the best demonstration, per https://discuss-cdn.kde.org/uploads/default/original/2X/e/e62b46923731ad9328bff6ecdd7a87b5961f77c6.png.

OBSERVED RESULT
The buttons overlap and the scroll toggle is invisible.

EXPECTED RESULT
They minimum size should be calculated in a manner which factors in how many buttons are present and their size, thereby allowing users with solely one button per end to minimize the panels further, and users with multiple buttons to not do so, ensuring that the scrollbar toggle and buttons are always visible.
