JOSM and photo layer

I am using JOSM on KDE opensuse leap.

Is there a way to toggle between an unpinned photo layer (window pane) and the main JOSM window with the usual window behavior ? Currently, toggling between the two is kinda painful, because when alt-tabbing from photo layer to JOSM edit layer would not hide the photo layer. It is as if the photo layer has a “keep on top” option, and to hide it I have to click minimize button. I’ve looked around for window pane properties and such but there isn’t anything out of order - nothing has special behavior ticked.

How do you guys do it? I would love to fast switch between JOSM edit layer, photo layer and mapillary photo layer.
