The behaviour of `PreventSurroundingPre` has changed in https://github.com/alecthomas/chroma/pull/618 so that apparently it now causes line wrapper tags to be no longer emitted, but we need some form of indication to split the HTML into lines, so I did what https://github.com/yuin/goldmark-highlighting/pull/33 did and added the `nopWrapper`. Maybe there are more elegant solutions but for some reason, just splitting the HTML string on `\n` did not work. Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
