Autocomplete disappears after typing

[kjgoodrick]

Issue Type: Bug

Describe the bug Autocomplete dissappears after typing in LaTex begin environments. Works after disabling vim.

To Reproduce 1.) Create basic latex file e.g.:

\documentclass{article}
\begin{document}

\end{document}

2.) Inside document type \begin and press tab to autocomplete begin environment

3.) Type any characters and autocomplete will disappear.

Expected behavior Autocomplete should stay open and filter suggestions as you type.

Behavior without vim enabled:

This appears to be caused by the multicursor, I see the same behaviour in other languages and it behaves as expected when there is a single cursor.
