cider-nrepl Debugger, wrong coor for atom

This is a minimal reproduction project for an issue with the cider-nrepl debugger stepping to a dereferenced atom.

The problem arises when debugging a function using an atom. In this particular case the atom is declared within a let binding. In order to reproduce the issue:

With CIDER or Calva (and probably any cider-nrepl client implementing the nrepl debugger protocol):

1. Load src/debug_atom_boom.clj
2. Evaluate the boom top level functionn
3. Evaluate the (boom) expression in the Rich comment

Expected: The debugger should at the @!a token and display the value 0.

Actual: Things go boom! (Different symptoms in CIDER and Calva).

Findings

Examining what happens, using Calva, the debug response has a coor of [3 1], meaning we should

1. navigate into the top level function and go 3 sexpressions forward
2. navigate down the @!a symbol and move 1 sexpression forward

But that second step isn't possible, the coor should be [3] as far as I understand things.
