框架的阴影仍然存在

Question

下面的设置在输入周围留下了边框阴影。我怎样才能让边框与背景完全融合？

\documentclass{article}
\usepackage{tcolorbox}
\tcbuselibrary{listings, breakable}

\newtcblisting
{internal}
{text only,
  breakable,
  colback=white,
  fontupper=\sffamily,
  arc=0pt,
  outer arc=0pt,
  boxrule=0pt,
  halign=left,
  fontupper=\small\sffamily,
  left=0pt,
  top=0pt,
  bottom=0pt}

\begin{document}

\begin{internal}
\LaTeX
\end{internal}

\end{document}

使用以下参数更新您的示例即可。

boxrule=-1pt
