It seems to be a bug but for me personally Plasma is not the reason I use KDE, I love KWin and krunner and all the other applications. KWin the window manager is very configurable so I can do a lot of things with it, krunner I launch my apps with it without using the mouse, the file manager is configurable and good for my use cases, the text editor is also very decent for small and quick edits. On top of that GTK2 and GTK3 apps are integrated as much as possible. If other DE matches you needs better and if it does it by default then I am happy for you I am not trying to sell you anything.
