Workaround a macOS cursor-related bug. 

This fixes an macOS bug that is only known to occur in fullscreen windows on the built-in displays of newer MacBooks with camera notches. When the mouse is moved near the top of such a window (within about 44 units) and then moved back down, the cursor rects aren't respected. This can cause the default cursor to be visible when it should not be.

(cherry picked from commit f1690e265e)
