Jooging keeps goinger after cursor moves out of focus

I have the same issue for glade tabs as presented here: forum.linuxcnc.org/21-axis/33925-glade-p...keys?start=30#227213
I'm on 2.9, and whenever i jog and move the mouse pointer into a tab, the jog continues after releasing the jog button.

I'm a quite experienced programmer, but it seems difficult to get key forwarding working.
Does anyone have an idea on how to approach this issue in a way that will work?
