Description

When editing files that fall into a given scope for language/grammar/snippets and an autocomplete-plus provider, both active, suggestions from the autocomplete-plus provider triggered by/for the same entry as the snippet cover the snippet one(s).

After the autocomplete-plus provider completion has been inserted, in the particular case the autocomplete-plus suggestion is a "key" suggestion (thus still triggering the snippet not shown), the tab key is pressed (or whichever is bound to snippet completion), the snippet is inserted and works as expected.

Steps to Reproduce

1. Edit a file with an active syntax highlighting for which both autocomplete-plus provider and snippets exist and are activated;
2. Start typing a word that should trigger a snippet and that triggers also an autocomplete-plus suggestion.

Expected behavior:
In the autocomplete list shown, both the snippet and the autocomplete-plus suggestions should be shown as separate items, ordered according to a user-given priority (snippets vs. autocomplete-plus).
The user should be able to insert with the key of choice either of them.

Actual behavior:
Only the autocomplete-plus suggestion is shown.
If the insertion of the autocomplete-plus suggestion still triggers the snippet one, the latter is not shown in a list, but if no other suggestions are shown, a tab enters the snippet.

Reproduces how often: 100% for cases that fall in those described above.
