…arget GTK matches the first destination target the drag source also offers, and 0.8.1 registered `application/vnd.portal.filetransfer` ahead of the URI targets. KDE (Dolphin) and Deepin (dde-fileManager) advertise that portal target on ordinary X11 drags too, not just from sandboxed sources. When it is chosen, `org.freedesktop.portal.FileTransfer.RetrieveFiles` rejects the key with `org.freedesktop.DBus.Error.AccessDenied: Invalid transfer`, `_resolvePortalFiles` returns an empty list, and the drop is silently lost. Register the URI targets first and demote the portal key and the bare STRING target to fallbacks, so the portal path is taken only when the source offers nothing better (a genuine sandboxed peer). No Dart change needed: `on_drag_data_received` already routes `text/uri-list` through `performOperation_linux`.

Register the URI targets first and demote the portal key and the bare STRING target to fallbacks, so the portal path is taken only when the source offers nothing better (a genuine sandboxed peer). No Dart change needed:
