This is another regression of Bug 562536.

In the past, the sash rects were overlayed by the controls of the children. Now the sash rects are detected on top of the children. 
As a result, the mouse pointer already changes when it is still a few pixels way from the sash. For instance, the mouse pointer already changes when still in the gutter to add breakpoints in the code. Setting the breakpoint still works, but it looks very counter intuitive to do this with a resize pointer.

This will get worse when the width of the sashes will be reduced.
