To move the scrollbar to currently selected ix-tree item as the current position in ix-tree is not saved persistently,

[NikhilSurana-k]

What happened?

The current position of selected item in ix-tree is not saved persistently, In our case each time the Items or sub items are selected in ix-tree,the entire component(i.e. TOC) is reloading, and the postion of scroll bar jumps back to the top.Here,we need to capture the scroll bar positon and set it back i.e. the ix tree should give an option to set the scroll bar position.

(We have more that 20,000 tree items to render in different hierarchy)
