Comments following not-really-affiliated keywords are becoming paragraphs

[Tom Alexander]

Emacs version: 29.1
Org-mode version: e1569918cc94253650781e83a09695739c93352f (latest in git)

Test document:
```
#+CAPTION: foo
# bar
```

This parses as a paragraph with the caption of foo and the body of "# bar" when 
it should parse as a regular keyword followed by a comment.

Relevant org-syntax[1] bit:

> a keyword with the same KEY as an affiliated keyword may occur so long as it 
> is not immediately preceding a valid element that can be affiliated. For 
> example, an instance of #+caption: hi followed by a blank line will be parsed 
> as a keyword, not an affiliated keyword.
