If you will set FOV of that window to 1 - you will have no ability to increase distance rather than that shown on the screenshot #1. If you will press “Zoom to fit” (#2)- WM will move your camera to far position even with that 1 as value(#3). And if after that you will try to scroll - your view will be bugged and teleported to primary position. (#4)
It is not huge bug but bug
