Layouts window preview doesn't refresh after delete

I’m cleaning out some saved layouts (Window->Manage Layouts), and noticed a minor refresh bug.

When I delete a layout, the blue selection highlight moves to the next saved layout in the list. But the preview of the saved layout to the right does not change to match.

Yeah, I get that as well. It looks like the checkboxes actually update, if the item below the original layout has a different configuration, just not the thumbnail.
