Description

Given the luasnip snippet

s({trig="bf", dscr="\textbf{}", snippetType="autosnippet"},
          {
            t("\\textbf{"), 
            i(1),
            t("}"),
          }
        ),

and the above nvim configuration cmp + luasnip exhibits the following behaviour.

If \textbf appears nowhere in the tex file before, it expands correctly to \textbf{}. If \textbf{} appears somewhere in the file instead it expands to bf}{}. If the luasnip trigger is changed to trig = '//' the expansion is correct every time.

Steps to reproduce

Open a *.tex file

\documentclass[12pt]{article}

\begin{document}

\end{document}

and enter the trigger bf once and after completing the snippet write the trigger again.

Expected behavior

The snippet correctly expands to \textbf{} every time.

Actual behavior

The snippet correctly expands to \textbf{} every time.

Additional context

I am aware the view.entries = 'native' is considered experimental. I changed my config to view.entries = 'custom'. This solved the issue.
