icon not always showing in history

[RiedleroD]

Some icons show up in the app-icon attribute, others do not.

these show up:

• NetworkManager sets generic icons, those show up
• when I set icon paths via notify-send, they show up

these don't show up, despite an icon clearly being set:

• when Firefox send notifications from websites
• when Telegram-desktop sends notifications with e.g. a profile picture

So my theory is that icons that aren't associated with a path or generic name are handled differently? I would still like to be able to read those from the history though.

There are other fields which can set the icon, either with the full path or pixel data.

they don't show up in the history as far as I can see. For example, this is a notificiation from a person liking my fedi post - the profile picture of the person shows in the notification itself:

{
	"app-name" : {
		"type" : "s",
		"data" : "Firefox"
	},
	"app-icon" : {
		"type" : "s",
		"data" : ""
	},
	"category" : {
		"type" : "s",
		"data" : ""
	},
	"desktop-entry" : {
		"type" : "s",
		"data" : "Firefox"
	},
	"summary" : {
		"type" : "s",
		"data" : "Luke"
	},
	"body" : {
		"type" : "s",
		"data" : "favorited your meow"
	},
	"id" : {
		"type" : "u",
		"data" : 76
	},
	"urgency" : {
		"type" : "y",
		"data" : 255
	},
	"actions" : {
		"type" : "a{ss}",
		"data" : {
			"default" : "Activate"
		}
	}
}
