It worked fine in Wayland under Plasma 5, but somewhere early in the 6 transition support was removed.
For anyone not aware it minimizes the window to its own titlebar. I find it faster and more intuitive than minimizing to a dock, and it’s easier to keep track of things when you can actually read the whole titlebar.
My blocker is the Window Shade button on Plasma.
