gtk menu has unnecessary empty space below its last entry on KDE Plasma Wayland session
Arch Linux, gtk 3.24.10, KDE Plasma 5.16.4 Wayland session. This bug does not occur on Plasma X11 session, gtk3 apps running on Xwayland are not affected.
My screenshot shows Brasero disc bruning software, but other gtk3 apps with a menu bar running natively on Wayland are affected. I tested both adwaita and breeze gtk themes, the result is always the same.
Steps to reproduce:
start KDE Plasma Wayland session
open any gtk3 app with a menu bar running natively on Wayland
open any menu
observe the empty space below the last entry of the menu
