Snippet doesn't load anymore.

Expected behavior: That my snippet expands.

Actual behavior: It doesn't expand:

Steps to reproduce This is at the top of my ~/.config/nvim/UltiSnips/tex.snippets file:

(...)
extends latex/math
(...)

And this is in my ~/.config/nvim/UltiSnips/latex/math.snippets:

global !p
texMathZones = [
    'texMathZone' + x for x in [
        'A',
        'AS',
        'B',
        'BS',
        'C',
        'CS',
        'D',
        'DS',
        'E',
        'ES',
        'F',
        'FS',

        ]
    ]
texIgnoreMathZones = ['texMathText']
texMathZoneIds = vim.eval('map(' + str(texMathZones) + ", 'hlID(v:val)')")
texIgnoreMathZoneIds = vim.eval('map('+str(texIgnoreMathZones)+", 'hlID(v:val)')")

    try:
        first = next(i for i in reversed(synstackids) if i in texIgnoreMathZoneIds or i in texMathZoneIds)
        return first != ignore
    except StopIteration:
        return False
endglobal

(...)

context "math()"
snippet frac "\frac{}{}" wA
\frac{$1}{$2}$0
endsnippet

• Operating System: Arch Linux
• Vim Version:

  NVIM v0.4.4
  Build type: Release

• UltiSnips Version: It should be the latest release version since I installed it with vim-plug and updated all packages with :PlugUpdate a few minutes ago.
• Python inside Vim:

  3.8.6

• Docker repo/vimrc: I don't really understand, what you need here.

Hint:

It worked before but I don't know exactly when it started to break.
