Popups appear on the next screen instead of being shifted away from the edge

With two screens connected, popups positioned too close to the edge between the screens will appear on the "next" screen. This is a bit confusing, because popups positioned too close to any other screen edge will just be shifted away from the edge and appear on the same screen as the active Qt Creator window. Feature or bug?

This happens both vertically and horizontally. See attached photo.
