Estoy tratando de tener solo un sistema global de notas a pie de página (numeradas), pero parece que tengo algunos problemas con los tcolorboxes rompibles. Muchas de las respuestas que he leído parecen demasiado avanzadas para mi simple requisito de un sistema único de notas a pie de página global.
Mi preámbulo es
\documentclass[a4paper,10pt,titlepage]{article}
\usepackage[utf8]{inputenc}
\newcommand{\myparagraph}[1]{\paragraph{#1}\mbox{}\\}
\usepackage[a4paper,margin=3.5cm]{geometry} %Sets the page geometry
\usepackage{url}
\usepackage{dirtytalk}
\usepackage{graphicx} % Package for \includegraphics
\usepackage{wrapfig} % Figure wrapping
\usepackage[T1]{fontenc} % Output font encoding for international characters
\setlength{\parskip}{1em} % Set space when paragraphs are used
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{mathtools}
\usepackage{hyperref}
\usepackage{mathrsfs}
\usepackage{mdframed}
\usepackage[breakable]{tcolorbox}
\usepackage[justification=centering]{caption}
\usepackage{soul}
% Note that we enforce things so that everything is numbered off of theorems
\theoremstyle{definition} % to avoid italicizing theorems
\newmdtheoremenv{theo}{Theorem}
\newtheorem{thm}{Theorem}[section] % reset theorem numbering for each chapter
\newtheorem{defn}[thm]{Definition} % definition numbers are dependent on theorem numbers
\newtheorem{rmk}[thm]{Remark}
\newtheorem{exmp}[thm]{Example} % same for example numbers
\newtheorem{crlry}[thm]{Corollary}
\newtheorem{lemma}[thm]{Lemma}
\newtheorem{problem}{Problem}[section]
%% HOW TO KEEP FOOTNOTES GLOBAL
\usepackage{footnote}
\usepackage{etoolbox}
\BeforeBeginEnvironment{tcolorbox}{\savenotes}
\AfterEndEnvironment{tcolorbox}{\spewnotes}
\usepackage{blindtext}
\usepackage{geometry}
%\usepackage{showframe} %This line can be used to clearly show the new margins
\newgeometry{vmargin={25mm}, hmargin={22mm,22mm}}
% Lets you use \blankpage to make a blank page
\newcommand{\blankpage}{
\newpage
\thispagestyle{empty}
\mbox{}
\newpage
}
Un ejemplo de mis notas a pie de página se ve aquí:
\begin{tcolorbox}[breakable]
\begin{defn}[Equivalence class]
Given an equivalence relation $\equiv$ defined on a set $S$, we define the equivalence class corresponding to any $a \in S$ as the set\footnote{If the equivalence relation in question is understood from context we'll sometimes just write $[a]$.}
$$[a]_\equiv = \{ b \in S | a \equiv B \}$$
\end{defn}
\end{tcolorbox}
En la siguiente imagen se ve un ejemplo de mi problema (tenga en cuenta los dos tcolorboxes, cada uno de los cuales comienza con la nota al pie "a"). Sin embargo, todo lo que hago fuera de tcolorboxes no tiene problemas, es global y se incrementa correctamente.
¡Cualquier ayuda será enormemente apreciada, gracias!

Tenga en cuenta que esto combina ambos \BeforeBeginEnvironmenty \renewenvironment. Tiene que ver con ejecutar comandos antes o después del argumento opcional.
