OK, here is the minimum script that demonstrates the bug:

=== script ===
#!/bin/bash
declare var="hello world"
declare -n ref
ref=var
echo $ref
ref=var
echo $ref

--- output ---
hello world
var


The equivalent "1 out of 4" script that works correctly:

#!/bin/bash
declare var="hello world"
func() {
  local -n ref
  ref=var
  echo $ref
  local -n ref  # the workaround
  ref=var
  echo $ref
}
func
