System tray icon not scaled correctly

Reproduction steps

Install Fluxer (not sure if Flatpak is required to reproduce) on Linux with KDE Plasma as the DE
Observe the system tray icon's size relative to surrounding icons

Expected behaviour

The system tray icon should scale correctly.

Actual behaviour

It seems to be a fixed size, based on the attached images. The one in Spanish is from another user and I do not know their display resolution, but my monitor is 4K and may explain why the icon is relatively smaller.
