Max window height not correct - overshooting forces monitor switch

The max of the Window Height slider corresponds to a height that extends the window beyond the bottom of the screen. This happend both on my external monitor and on my laptop monitor with external monitor detached.

When using Guake on an external monitor (set as primary in Gnome), overshooting the real max height results in the the Guake window jumping to my laptop monitor, even though it has less pixels in height. It also jumps to the right side of the laptop screen, although my setting is to keep it to the left.

Running Guake 0.8.3-1 on Fedora 23 with Gnome 3.18.
