When the window size is bigger than the monitor's size, guiNode's translations mess up

jMonkeyEngine version: 3.2.0 alpha

For example, my desktop's monitor is 1980x1080, and when I set the window's height around 1060 or higher, the translations of guiNode's children are messed up. They work fine on full-screen mode (1980x1080).
guiNode's children whose y values are small are fine, but children with higher y values aren't placed properly.
The simplest way to test this would be to place something like BitmapText at the top of the screen (like this: https://anonimage.net/image/hHiwaZS5Qm) and it will be displayed properly until the window gets too tall for your screen (e.g., 1920x1080 windowed, due to the frame), for me the text got cut off.

I know that it probably isn't a good idea for the user to set the window size too big for their monitor, but I still don't want it to produce bugs like this. Hopefully someone more skilful than I could fix this.

Start by reproducing the issue with guiNode children such as BitmapText in a windowed mode whose size exceeds the monitor, then compare the translations at small and large y values with fullscreen mode. Done means guiNode children remain correctly positioned and are not clipped when the window is too tall for the monitor.
