为什么当我在 tikzpicture 中移动节点时我的包含图形会不断移动？

Question

我正在尝试创建下图

下面是我的示例代码。我似乎无法让 AR 处于正确的位置。每次我改变 x 位置时，整个图形都会移动。我该如何将所有东西固定到位？

\documentclass{article}
\usepackage[utf8]{inputenc}

\usepackage{tikz}
\usepackage{float}
\usepackage{subfig}

\title{test}
\author{test}%

\date{January 2022}

\begin{document}

\maketitle

\tikzset
{%
  label/.style={scale=0.7,fill=white,thick,draw=white!80,anchor=south west,align=left},
}

\def\lsep{-0.2}
\begin{figure}
\centering
\hspace{-7.5cm}
\subfloat{
\begin{tikzpicture}
    \node[label] at (-0.5,\lsep)    {\strut$A^{L}$};
    \node[label] at (-0.5+4,\lsep)  {\strut$A^{R}$};
    {\includegraphics[width=0.4\columnwidth,height=5\columnheight]{example-image-a}}\hspace{1cm}
    {\includegraphics[width=0.4\columnwidth,height=5\columnheight]{example-image-a}}
\end{tikzpicture}
}
\end{figure}

\section{Introduction}

\end{document}

试试这个代码。这四个元素是相对定位的。因此它们tikzpicture会作为一个整体移动。

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{positioning}

\usepackage{float}
\usepackage{subfig}

\usepackage{showframe}
