Created attachment 182596 [details] Icon staying to same "default" file manager, from icon theme. This only happens in Dolphin, using the papirus icon theme, for example, changing to "dino" in Applications category works for discord but not Dolphin(included screenshot).
Created attachment 182597 [details] Dino icon in Menu Editor from Papirus and working in Discord header.
I guess it's due to https://invent.kde.org/system/dolphin/-/merge_requests/945, but limiting the icon to not be able to be changed either whatsoever is a bug or intended design?
Created attachment 184937 [details] A better view of the problem This is in the recent 25.08.1
This is very similar to https://bugs.kde.org/show_bug.cgi?id=503122
