I tried and things seems to be working fine now.

And the warnings are still present :)

I have a few minor comments.

Nitpick: Just preview-queue without parenthesis will be the same.

Do we need `save-match-data' here? Nothing inside seems to be making use

What if `org-buffer' gets killed when the preview timer triggers?
