Comment # 11 on bug 1026999 from Michael Lashkevich

I experienced problems with system tray in 5.8.7.1 version from
https://build.opensuse.org/project/show/KDE:Frameworks5:LTS. Just in this
version the system tray does no show the FireTray and AllTray icons. The icons
are completely absent. There is even no free space for them, so that when I
minimized Thunderbird with the FireTray extension or any application started
with alltray, I could not restore them. With older 5.8.7 from LTS before the
last update or with 5.8.6 from base distribution the system tray works well.
