Webpack obfuscator and Webpack banner plugin do not work together

I am trying to obfuscate my javascript code and after adding webpack-obfuscator as a plugin, webpack.BannerPlugin stopped working.
I've read that I need to add @license or @preserve to the license, but it does not help, can anyone help me?

首先复现 webpack-obfuscator 插件与 webpack.BannerPlugin 之间的交互，包括报告中的 @license 和 @preserve 注释变体。分别启用每个插件后比较生成的 bundle；当混淆和 banner 能够协同工作且不会丢失预期的许可证注释时，该 issue 即完成。
