Looks like a Pygments issue.

$ cat minted-gh460-escapeinside.txt

LINE

$ pygmentize -f latex -P stripnl=false minted-gh460-escapeinside.txt
\begin{Verbatim}[commandchars=\\\{\}]

LINE

\end{Verbatim}
$ pygmentize -f latex -P stripnl=false -P escapeinside=\|\| minted-gh460-escapeinside.txt
\begin{Verbatim}[commandchars=\\\{\},codes={\catcode`\$=3\catcode`\^=7\catcode`\_=8\relax}]
LINE
\end{Verbatim}
