window: fix vertical pullback in checkOffscreenPosition using width

When a window ended up entirely above the screen, the fallback position
used screenArea.width() / 4 instead of height() / 4, pulling the window
back by the wrong amount on non-square screens. Use height() for the
vertical branch to match the other three directions.
