Could you please stop that reassigning game? You are right, it's either on shared-mime-info or the qt integration, now the result of the testcase provided is correct on GNOME (see comment 5), it's also correct on a cloud instance (e.g no desktop integration) so it's only buggy on KDE, you should rather reassign to the Qt integration, unsure what the right component for that is though
