pgfplot 的 smithchart 中刻度位置发生不必要的变化

当我使用 pgfplot 的 smithchart 并将小数点分隔符改为逗号时，x 轴刻度的位置发生了一些奇怪的变化。

一个简单的例子：

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

\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\usepgfplotslibrary{smithchart}

\pgfplotsset{ every axis label/.append style={font=\scriptsize}, every tick label/.append style={font=\scriptsize}}

\pgfkeys{/pgf/number format/.cd, use comma, set thousands separator={ }}
% THIS IS CAUSING THE PROBLEM

\begin{document}

\begin{figure}[t]
    \centering
    \begin{tikzpicture}
    \begin{smithchart}[scale=1]
    \addplot[mark=*, only marks, is smithchart cs] coordinates {
        (0.23076923, -0.51282051) (-0.32873098, -0.45626227) (-0.55950021, 0.05655824) (-0.23076923, 0.51282051) (0.32873098, 0.45626227) (0.55950021, -0.05655824) (1,0) (-1,0) (0,0)
    };
    \addplot[draw=blue,fill=blue, mark=*, only marks, is smithchart cs] coordinates { (0.10750507, -0.12170385)
    };
    \path[draw=black, dashed] (1,0) circle (1.6cm);
    \end{smithchart}
    \end{tikzpicture}

\end{figure}

\end{document}

x 轴上的 0.2 和 0.5 高于其他数字。这个问题有解决办法吗？

为刻度标签添加文本深度：

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

\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\usepgfplotslibrary{smithchart}

\pgfplotsset{ every axis label/.append style={font=\scriptsize}, every tick label/.append style={font=\scriptsize,text depth=.25ex}} % text depth added

\pgfkeys{/pgf/number format/.cd, use comma, set thousands separator={ }}

\begin{document}

\begin{figure}[t]
    \centering
    \begin{tikzpicture}
    \begin{smithchart}[scale=1]
    \addplot[mark=*, only marks, is smithchart cs] coordinates {
        (0.23076923, -0.51282051) (-0.32873098, -0.45626227) (-0.55950021, 0.05655824) (-0.23076923, 0.51282051) (0.32873098, 0.45626227) (0.55950021, -0.05655824) (1,0) (-1,0) (0,0)
    };
    \addplot[draw=blue,fill=blue, mark=*, only marks, is smithchart cs] coordinates { (0.10750507, -0.12170385)
    };
    \path[draw=black, dashed] (1,0) circle (1.6cm);
    \end{smithchart}
    \end{tikzpicture}

\end{figure}

\end{document}
