What is this change?

I do not know, I did not make this change. I guess when I pulled the recent
change from master, this one showed up.

 
         // If we're at the stopNode, we should try to scroll it but we shouldn't bubble past it
         bool shouldStopBubbling = stopNode && *stopNode && curBox->node() == *stopNode;
