How to prevent clicking off selected row from deselecting it?

When I click off a selected row the Tree component will deselect all my selections even though I am not calling deselect() on those nodes.

I would like to prevent this behavior, or at the very least attach a listener so I can update the state of my application when this happens. I tried many workarounds, but am a bit stuck and would appreciate any help.
