Neighbour workspaces are a very small drop target in portrait mode
My monitor is in portrait orientation, 1050×1680. Since the Shell redesign that rearranged workspaces horizontally instead of vertically, it has become very difficult to move windows to a new workspace with the mouse. When there is only a single workspace, the new (empty) one on the right is very narrow, only 13px wide in my case.
Once I managed to move a window there and the workspace previews appear at the top, it seems to get wider, to 40px. That still feels small and I often miss the drop target even at that width.
It looks like this width is proportional to the monitor width. Could it be made a minimum width so it never gets too small?
