Separator "::" -> what is it for in headlines?

Why does the separator "::" work with headlines?

Example:

* Headline with separator :: This would be the description of a list, 
but what is it here?

> 2.6 Plain Lists
>
> /Description /list items are unordered list items, and contain the 
> separator ‘::’ to distinguish the description term from the description.

It doesn't seem to have any effect for me, it gets handled as part of the
headline, both in fontification and in exports:

Which is, as I understand it, as it should be, since it doesn't have any
special meaning in headlines.

In your case it seems indeed to be getting fontified as if it were a list.
What version of Org do you have? I am using 9.5 on Emacs 27.2.

Hi!

I have updated to:
GNU Emacs 27.2 (build 1, i686-w64-mingw32)
Org mode version 9.4.5 (9.4.5-29-gc43041-elpa

Same issue:
* *To **the left of* :: it's bold

Note: I coudn't find Org mode version 9.5, just 9.4.5

Best regards,
Ypo

I can reproduce. The issue appears only in level 1 headlines because of
wrong regexp in font-lock-keywords. The attach patch should fix the
problem.

Best,

Subject: [PATCH] Fix description list item regexp when fontifying "*" items

* lisp/org.el (org-set-font-lock-defaults): Avoid fontifying headlines
with "::" as description list items.  Lists can start with "*", but
"*" must not be at the beginning of line.  Old regexp did not require
whitespace before "*" in description list items.
