我正在寻求为列表添加突出显示。我尝试过以下技术：https://tex.stackexchange.com/users/23765/siracusa在问题中突出显示代码列表中的文本，同时保持语法突出显示
但是我遇到了一个问题，如下面的示例所示。我希望我的列表位于 tcolorbox 中。当它不在 tcolorbox 中时，突出显示会按预期工作。当它在框内时，突出显示会正确呈现在正确的位置，但它不会显示，因为 tcolorbox 似乎绘制在它上面。
有没有办法在框顶部（但仍在文本下方）绘制突出显示？我真的很想保留突出显示解决方案的核心，因为它与 listings 包配合得很好。
还要注意的是，任何涉及手动调整单个代码块的解决方案都不是一个选择。它们的内容是由另一个程序生成的，而且有数千个。
