List view: Selecting a block on the canvas should expose that block (or its lineage) in list view

[jameskoster]

When a container block is collapsed in list view, selecting a child of that container on the canvas doesn't provide any visual feedback in list view. You must manually expand the relevant container. Video example using the Columns block:

list.view.mp4

A couple of potential solutions:

1. Automatically expand the relevant container, down to the selected block
2. Apply a unique visual treatment to the collapsed parent to indicate a child is selected

The first option seems the most straight-forward to me. Perhaps there are other ideas though?
