Reason for revert:
Landed suppression in Chrome's LayoutTests/TestExpectations

Original issue's description:
> Revert of fix for conic fuzz (patchset #3 id:40001 of https://codereview.chromium.org/2350263003/ )
>
> Reason for revert:
> See if this fixes the layout tests.
>
> Original issue's description:
> > fix for conic fuzz
> >
> > A fuzzer generates a conic that hangs when drawn.
> > The quads that approximate the conics move up and down
> > in y, confusing the renderer.
> >
> > This fix ensures that the split conic maintains the
> > same y direction as the original conic.
