getScrollAccessor on window seems wrong

[satazor]

dom-helpers/src/getScrollAccessor.ts

Line 19 in 536ae60

win.scrollTo(win[offset], val)

When offset is pageYOffset, scrollTo will be invoked with scrollTo(currentPageYOffset, newPageYOffset). When offset is pageXOffset, scrollTo will be invoked with scrollTo(currentPageXOffset, newPageXOffset).

This doesn't seem to be right. What we want to do is to preserve the value of X when we are changing Y and vice-versa.
