[Bug][Grid] Keyboard navigation broken when using `navigatable`

[filipKovachev]

Description

The following issues arise with the current keyboard navigation when navigatable=true is being used:

Arrow keys - when you select a cell to be able to navigate and then keep pressing down and then up, it's not posible to come back to the first record. You need to use the mouse.

Page up/down keys work the other way round, also sometimes is not possible to come back to the first record, the scrollbar does not show the current position.

It starts to work correctly after using the arrow keys and page up/down keys alternatively couple of times

2. Grid with navigatable=false:
   Arrow,Page up/down keys and scrollbar work correctly

3. Grid with navigatable=true and nested inside Window:
   Works the same way as not nested - the same problems occur

4. Grid with navigatable=false and nested inside Window:
   Arrow keys move the window instead of navigating the grid
   Page up/down don't work at all
