As described in the long title; Package qt5-qttranslations is responsible for providing Qt applications necessary aspects to render Plasma and the applications RTL when the desktop locale is set to RTL (Such as Arabic), however, the package, although available in fedora repos, is not installed by default in KDE Spin, resulting in desktop rendering LTR with the correct language (Shape 1), however, installing the package and restarting the device would render everything correctly as expected (Shape 2). With this, the package should either a) be available with KDE Spin by default, or b) be triggered to be installed upon selecting a RTL locale from Plasma Settings (YaST has such behaviour to install additional packages upon selecting certain locales, not sure Plasma provides such functionality).
