In the tree, when the user presses the left arrow key:

If the current selected node is a leaf, the selection should move to the parent
If the current selected node is not a leaf:
- If it's expanded, collapse it
- If it's collapsed, move selection to the parent

This is not yet implemented, but we need it to match Swing's behaviour.
