Unexpected autocomplete inside a <li> tag

[mossarelli]

Using Atom 1.12.4, autocomplete-snippets 1.11.0 and snippets 1.0.4

This is the custom snippet:

'.text.html.basic':
  'hyperlink':
    'prefix': 'a'
    'body': '<a href="#$1" class="underline">$2</a>$3'

When using a outside li, the autocomplete makes the snippet "hyperlink". When using it inside li, it wants to use a snippet called "anchor" which is not defined as custom.
The picture below shows the issue:

I've searched the issues and there's only one other issue resembling this, but it's not for HTML.

Solved by changing the name of the snippet from 'hyperlink' to 'custom a'.

Is there a name conflict error with the word hyperlink?

Please clarify in the documentation, what names for snippets can be used and can't.
