Please describe your issue in as much detail as possible:

In my system, the Steam is installed as Flatpak.
When I launch Steam, instead of the correct icon in the tray, the stub is displayed:

The problem is observed after the update to Fedora 40 Kinoite Beta (KDE 6). All ok on the Fedora 39 Kinoite (KDE 5.27.x). Therefore, I suspect that in KDE 6 there have been some changes regarding the icons in the tray, and maybe this should be taken into account on the Steam side.

Steps for reproducing this issue:

1. Just run Steam Flatpak on the KDE 6 environment.
