nm-applet sometimes does not display in the system tray

[AlxTray]

I have two monitors so 2 bars, and sometimes the nm-applet system tray is only on 1 bar and not on the other, on both or on none. Waybar and nm-applet are both started in Hyprland’s exec-once.

I have tried this with other bars and they seem to work fine, so I can only see this as somehow a waybar issue. Weirdly though this only will happen at startup so, if I kill nm-applet and start it again, it will be on both bars each time.
