There is an edge case when parsing export snippets:
@@html:fo aksjdaksjd ajs d
askdjas aksj daj sao@@
Our current parser recognises the opening "@@html:" as a standalone
snippet.
Unless I misunderstand something, it is not intentional.
The fix is attached.
Nicolas, unless you have any objections, I will install the attached
patch to bugfix.
Best,
Ihor

Subject: [PATCH] org-element-export-snippet-parser: Fix snippets without

@@html:fo aksjdaksjd ajs d
askdjas aksj daj sao@@
