  The issue

  When booting, not all system tray items are shown When ags is restarted, system tray remains empty.

SystemTray.item id's:

[
    "chrome_status_icon_1",
    "chrome_status_icon_1",
    "KDE Connect Indicator",
    "nm-applet",
    "chrome_status_icon_1",
    "Galaxy Buds Client",
    "blueman"
]

What i see here is that there is a listener for added and deleted, but existing items are not added.

I tried to fix but know too little about ags to do so, but maybe in Tray.js/Tray you could add them in the setup() function?

If you need anything let me know
