Steps to reproduce given the above info

source file for reproduce the ctags issue:

Any Tex/LaTeX file: can also reproduce on this:

\documentclass[12pt]{letter}

\address{Somewhere}
\begin{document}
\begin{letter}{Some address}
  \opening{Dear Sir or Madam,}

  Some text


  \closing{Yours sincerely,\\
    \fromname{John doe}
  }
\end{letter}
\end{document}

minimal vimrc (neccessary when this issue is about some Vim LSP client):

N/A (not related to LSP client, I don't think)

1. Open a Tex/LaTeX file
2. Run Vista

Expected behavior
Vista viewer should come up

Actual behavior
No Vista viewer, warnings come up.

Screenshot or gif (if possible)

Possible fix:

I don't know too much about ctags. I saw that there were these two lines in autoload/vista/types/uctags/tex.vim and removing them seems to "fix" the issue:

These two options are not available in the recent ctags, I have included your patch in #466, hopefully, it won't bring other side effects as I'm really not a tex user.
