The hasHierarchy ? [ rootBlock ] : rootBlocks bit and the associated code in the withSelect function lower down in this file means that when a child block is selected, ListView zooms in to only show a limited part of the tree.

So that could be changed as well. I wonder if it might be good to make the changes to ListView's logic a separate PR?

I couldn't quite wrap my brain around this logic — its very strange to me, but its the existing behavior. I'm happy to change it, but it might make more sense in a separate PR, perhaps along with adding a sidebar for this list view.
