Mouseleave event windows not firing when leave from top of window


I have a window that is frame-less and when using the jquery hover function, the mouseleave event does not fire when I leave the window from the top. From the bottom it works fine and adding the frame back to the window works fine in both directions. I need the window to be frame-less so is there anything I can do to make this work? This is only an issue on Windows 10. I tested on OSX and it works fine in all directions there.
