Panel is positioned at the bottom edge but shown when pointer is at the top edge.

1. Set panel.autohide = true
2. Set panel.position = top
3. Launch wf-panel
4. Set panel.position = bottom

Expected behaviour: panel is positioned at the bottom, shown when pointer is at the bottom edge.
Actual behaviour: panel is positioned at bottom, shown when pointer is at the top edge.

Fixed by #306 ! Seems #235 and #421 were duplicates…
