This test document has 1 paragraph:
```
foo
bar
baz
```
which parses as:
```
(section
(paragraph "foo\nbar\nbaz\n")
)
```
This test document should have 1 paragraph but org-mode is parsing it as 2:
```
foo
:end:
baz
```
which parses as:
```
(section
(paragraph "foo\n")
(paragraph ":end:\nbaz\n")
)
```
The paragraph documentation[1] states that:
> Empty lines and other elements end paragraphs.
But the document contains no empty lines and we can see in the output that it only contains paragraphs.
