Dropbox is translated into many languages. Because it is an extra-data app, even if the appdata specified <translation>, the build infrastructure would not extract the supported applications. (Although it's a Qt app, AFAICT it doesn't use the normal Qt translation machinery anyway.)
Discussion on #flatpak suggests that the right way to handle this situation is to list <languages> manually.
