Including python syntax sets conceillevel (bad interaction with LaTeX buffers)

Hi ---
I have installed `jedi-vim` and I find it really nice to edit python files. But I came across a problem that I am unable to solve --- it makes editing of LaTeX files much more complex. The problem is the following. I have in my `.vimrc`:

```
Plug 'davidhalter/jedi-vim'
autocmd FileType python setlocal completeopt-=preview
```

And when I edit a LaTeX file, the `$...$` marks that define an inline math disappears unless the line is under the cursor. See:

Case 1, cursor in different line of the math formula (the cursor does not appear on screenshot, but believe me...)


Case 2, few instant after, cursor in the same line:


This make LaTeX files almost impossible to edit. Is there a way to restrict all of the `jedi-vim` effects to python buffers?

PD I checked that commenting out the plugin will remove the problem.
