It seems like this was once fixed for Windows: https://github.com/docker/for-win/issues/4113

Unfortunately, it's still broken in KDE Plasma 6, and I couldn't find an easy workaround to fix that either as the org.freedesktop.StatusNotifierItem dbus interface does not expose any properties with Docker Desktop on Linux.

It's the same on Linux Mint Cinnamon with the light theme, very hard to see the icon.
