Three of the test cases I added under Bug 130983 show slightly different scroll amounts when run under the WK1 DumpRenderTree compared to the WK2 TestRunner.

The overall test case works properly, but the numerical (pixel) amounts of the scroll moves are not the same:

WK1: Position after scroll: 58
WK2: Position after scroll: 70

This may not be an error at all, but just a byproduct of the difference in even handling between the two platforms (perhaps an extra scroll moment step is received for WK2).
