Been using KDE Plasma (on Manjaro) for about a year and a half now, to great satisfaction.

Since about 2 weeks (I presume after the last time I upgraded) the window behavior on activation has changed.

I've kept the "Virtual Desktop Behavior" (Window Management -> Window Behavior -> Advanced -> Virtual Desktop Behavior) always on "Switch to that Virtual Desktop".
It is still configured that way, but the actual behavior brings the window to the current desktop now, which I find extremely annoying.

I've already tried to apply it with the other setting (bring it to the current desktop) and then apply it again on the switch to desktop one, but to no avail.

Is this a recently introduced bug or something wrong on my end? Is there something else I can try?

Guess I'll answer my own question as it seems this finally got picked up and fixed (though not in a release yet apparently):
