Description Quinten Kock 2023-11-24 13:06:11 UTC 
SUMMARY
Sidebar buttons are one pixel removed from the edge, making them harder to hit


STEPS TO REPRODUCE
1. Move cursor to edge of screen at position of a sidebar button like "Projects"
2. Click

OBSERVED RESULT
The entire sidebar is clicked, instead of the specific button that was aimed for

EXPECTED RESULT
The button touches the edge of the screen and is thus activated

Decrease padding for KMultiTabBar

In effect revert https://invent.kde.org/plasma/breeze/-/merge_requests/368

Visually having at least a one pixel padding is important but this
decrease the usuability as it breaks the Fitts's Law.

A long term solution would be to redirect the click event to the nearest
button, but for now let's just fix the usuability issue.
