This happens on X11 too. Apparently the panel counts as a window for the purpose of defining "others". Not sure whether this is intentional or a bug though.
Comment 2 Patrick Silva 2018-11-16 14:16:22 UTC 
another way to reproduce the bug:
start Wayland
open two apps that run natively on Wayland, let's say Dolphin and Kate
maximize the window of both apps
press alt+tab and hold alt key to keep the task switcher on the screen
Panel has the same shadow shown in my screenshot.
My task switcher is "Large icons".

On Plasma 5.23 beta I no longer see the shadow seen in the screenshot.
I only see a slight difference above Plasma panel instead.

Seems to be fixed (or at least improved) now, yeah.
