When I search for “panel” nothing shows up.
Technically not a bug, hence I file it here, but a oversight nonetheless.
Let me know what you think 
sorry for formatting the link so weirdly, I cannot post links, made a seperate dicsussion on this topic as well.
ah, it is under plasmashell.
Suggested fix:
Multipurpose shell based on Qt5/QtQuick2/KF5. Use this for bugs in Plasma 5’s shell, desktop panels, widgets and applets.
I added the keywords “desktop” “panels” and “widgets” to the description, so you can CTRL+F them.
