I added a reftest for this defect as per Alexey's suggestion in comment #4. 
I am new to webkit. How do I get pixel results for this? I tried running run-webkit-tests --pixel, but it did not generate any pixel results. Could you please point me to a similar defect which I can refer to?

It is not needed. scrollToYOffsetWithoutAnimation has got implementation only in the base class. I added it because I saw similar usage in RenderListBox. I will remove this.
