Code.compile_quoted/2 leaves errors in parallel compiler accumulator

Current behavior

① Create the new project with mix new diagnostics_compiler_test.
② Change the code of the only module to be

defmodule DiagnosticsCompilerTest do
  Code.with_diagnostics(fn ->
    try do
      {:ok, Code.compile_quoted({:fn, [], [{:->, [], [[], quote(do: unknown_var)]}]})}
    rescue
      err -> {:error, err}
    end
  end)
end

③ Run mix compile.

---

The result would be a compile error provoked [AFAICT] by Code.compile_quoted/2 leaving the error in the spawn_workers/8 accumulator errors.
