填充绘图区域会改变另一个绘图的误差线

我有以下情节：

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.16}
\usepackage{pgfplotstable}
\usepgfplotslibrary{fillbetween}
\pgfplotstableread{
  X Xminus Xplus
  1.13 0.1 0.2
  1.14 0.02 0.7
  1.145 0.23 0.23
}\data
\pgfplotstablegetrowsof{\data}
\let\numberofrows=\pgfplotsretval

\begin{document}
\begin{tikzpicture}[trim axis left,trim axis right]
    \begin{axis}[y=-\baselineskip,
        scale only axis,
        width             = 6.5cm,
        enlarge y limits  = {abs=0.5},
        axis y line*      = middle,
        y axis line style = dashed,
        ytick             = \empty,
        axis x line*      = bottom
      ]
      \addplot+[mark=none, update limits=false,color = black] coordinates {(1.1, -1) (1.1, \numberofrows-0.5)};
      \addplot+[mark=none, update limits=false, dashed, color = black,name path=errmin] coordinates {(1.05, -1) (1.05, \numberofrows-0.5)};
      \addplot+[mark=none, update limits=false, dashed, color=black,name path=errmax] coordinates {(1.15, -1) (1.15, \numberofrows-0.5)};
      % \addplot+[mark=none, update limits=false, fill=black!10] fill between [of=errmin and errmax];
      \addplot+[only marks, blue, thick, mark=*, solid, error bars/.cd,x dir=both, x explicit]
        table [x=X,y expr=\coordindex,x error minus=Xminus, x error plus=Xplus]{\data};
      \end{axis}
    \end{tikzpicture}

\end{document}

这给了我预期的结果：

情节还行，但没有填充

当我取消注释该行以填充虚线之间的区域时

      \addplot+[mark=none, update limits=false, fill=black!10] fill between [of=errmin and errmax];

我得到了奇怪的错误标记（实际上条形图是正常的，但标记以一种奇怪的方式移动了）

带有奇怪错误的图表

我在这里做错了什么？我无法弄清楚这里的问题是什么。这是预期的行为吗？

这种混乱是由于trim axis right（在这种情况下）不需要/无论是否存在都不会改变输出而造成的。

该图显示了上述代码的结果

在此处输入图片描述

而是fillbetween使用简单fill的矩形，其边界的确定方式与 相同fillbetween：

\documentclass[margin=3mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.16}
\usepackage{pgfplotstable}
\pgfplotstableread{
  X Xminus Xplus
  1.13 0.1 0.2
  1.14 0.02 0.7
  1.145 0.23 0.23
}\data
\pgfplotstablegetrowsof{\data}
\let\numberofrows=\pgfplotsretval

\begin{document}
\begin{tikzpicture}[trim axis left,trim axis right]
    \begin{axis}[y=-\baselineskip,
        scale only axis,
        width             = 6.5cm,
        enlarge y limits  = {abs=0.5},
        axis y line*      = middle,
        y axis line style = dashed,
        ytick             = \empty,
        axis x line*      = bottom,
      ]
      \fill[gray!30] (1.1,-1) coordinate (a) rectangle (1.15,\numberofrows-0.5) coordinate (b);
      \draw[densely dashed] (a) -- (a |- b);
      \draw[densely dashed] (b) -- (b |- a);
      \addplot+[only marks, blue, thick, mark=*, solid, error bars/.cd,x dir=both, x explicit]
