Middle click paste in Plasma

A long time Unix user, I much prefer select with left and optionally right click, and to use middle-click to paste. In X11, it means using PRIMARY rather than CLIPBOARD. This QT merge request led me to believe this would finally be possible in Plasma under Wayland. But when I try it out, It still doesn’t work for me. I start a konsole, mark something, and middle click. Nothing happens.

Is this still not expected to work, or do I have to do something to explicitly enable it?

It looks like to be in process but will take a time accord this bug info:
