Steps to reproduce,

1. Put test.el in the current working directory.

   (package-initialize)
   (require 'use-package)
   (use-package treemacs)
   (use-package lsp-mode)
   (use-package dap-mode
   :custom
   (dap-auto-configure-features '(sessions locals controls tooltip repl))
   :config
   (use-package dap-python
     :after python
     :custom
       (dap-auto-configure-mode t)
       (dap-python-debugger 'debugpy) ; pip3 install debugpy
       (dap-python-executable python-shell-interpreter))
   :hook
   (python-mode . dap-ui-mode)
   (python-mode . dap-mode))

2. Run emacs -Q --load test.el.

3. Run M-x dap-debug (dap-python) and choose the file option.

4. Interact with one of the Treemacs windows spawned by dap-debug (this is important).

5. Let the debugger finish.

6. Toggle the Treemacs window by M-x treemacs treemacs.
