I've discorered it when reinstalling OBS 1- Bookmark an installed app 2- Remove the same app 3- Reinstall the same app 4- Search for the same app 5- Right-Click on the same app Result: The Context Menu states that the app is bookmarked, even though it's not actually bookmarked because of the removal.
Created attachment 177049 [details] "Remover dos Favoritos" means "Remove from Bookmarks"
Could this also be fixed by https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/5047 ? It seems like it should!
