@skrustev Build fails with error:
Property '_pinnedRecordIDs' does not exist on type 'IgxGridBaseDirective'

Additionally pinning throws error in treegrid:
Cannot set property 'ghostIndex' of undefined

Issues:

• Pinned rows order is not retained correctly in TreeGrid.
  To reproduce pin the second row in tree grid and then the first row. Order in pinned area should be second row and then first row since this is the order of pinning.
• Jump to + Paging - Not sure what the expected behavior is, but at the moment if the result is on another page the button is shown but clicking it does nothing. It should either change the page to show the result or the button should not be shown if the result cannot be scrolled (is on another page).
• Jump to + Group by - If the target ghost row is in a collapsed group, the button scrolls to an incorrect index. It should either scroll to the group or preferable it should also expand it to show the ghost row.
• Jump to + Tree Grid - Same as with grouping. If the target is in a collapsed parent it cannot be scrolled to.

This PR should be merged after #7192, since it contains changes that are required for the Tree Grid Jump To on another page to work.

Grid:

• Grid+ Paging - In Grid if you go from a page that has no scrollbar to a target row on a page with scrollbar the row is not scrolled in view.

Steps to reproduce:

1. In the gridRowPinning sample in the grid set page size to 5.
2. Pin the last row and expand a row above it.
3. Go to the last page and use the "Go to" button.
   Page is changed but the row is not scrolled in view.

Hierarchical Grid:

• In root grid if a row in the middle is pinned and all rows are then expanded, "Go To" cannot scroll to the correct row.

Steps to reproduce:

1. In the gridRowPinning sample in the hierarchical grid, pin a row in the middle (8).
2. Expand all rows via the header button and use the "Go To" button.

• (This will be logged as limitation.) When using "Go to" in a child grid and target row is not visible in parent, the parent is not scrolled so that the target is visible.

Steps to reproduce:

1. In the gridRowPinning sample in the hierarchical grid, expand the first row.
2. Pin the last row in the child grid and scroll both child and parent to the top.
3. Use the "Go to" button in the pinned row.
   Child is scrolled down, but parent is not, so the target is not visible. User has to scroll the parent down to see the target.
