Re-adding content in Table causes table to lose scroll position (#14581)

Re-adding content in Table causes table to lose scroll position (#14581)

At this moment behavior of restoring scroll position more like as in
7.2.6. But restoring is only in case of removeAll() - addAll() (or add()
one time - then restore index is reset).

In 7.2.6 restoring of scroll position was the result of client defect
(scrolling in lazyScroller was not changed if variable "firstvisible"
fromserver was 0). This "defect" was fixed in one of the patches.
