[Bug]: Workspace Tree View keyboard navigation issues

[audrius-u]

What happened?

When navigating long Workspace Tree View (and probably other tree controls) using keyboard, some issues happen:

1. End key should focus the last visible item, but brings cursor beyond the last item in a tree.

2. When a long tree branch (lots of files in a directory) is open, the parent node is open and above the visible part of tree and not visible, and any visible child item is selected, pressing the Left arrow is expected to move focus to the parent node and bring it into the view, and repeated press of Left arrow should close it, but instead leaves one or more dangling child nodes that disappear later on any other tree action.

Steps to reproduce

Ways to reproduce:
1. Press End key when Workspace tree view is focused. Focus highlight disappears. Press Up key and the bottom element gets focused.
2. Have a large list of entries under folder node, list should contain more items that would fit into tree viewport. Expand the nodes, scroll the view down so that parent node moves through the top. Highlight (using mouse) any visible child entry, press Left key. Focus jumps to parent node, but parent node does not get into the view. Press Left again, parent node closes, but some of its child nodes remain visible until next tree action.
