The org-modern-indent package relies on org-indent having finished preparing a buffer to add its own customizations. Currently it relies on a timer mechanism to watch org-indent-agentized-buffers and execute once a buffer has been prepped by org-indent.
That leads to some downstream issues in particular use-cases (https://github.com/jdtsmith/org-modern-indent/issues/11) Although there are some workarounds for the particular issue above, a cleaner solution would be org-indent calling some hook at the end of the preparation. As per link above, jdtsmith proposes to add such call in org-indent-initialize-buffer: ;; Job is complete: un-agentize buffer. (unless interruptp (setq org-indent-agentized-buffers (delq buffer org-indent-agentized-buffers)) (run-hook-with-args 'org-indent-buffer-init-finished buffer)) ;; <-- added -- Alexandre Avanian
