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?

Start by reproducing the interaction between the webpack-obfuscator plugin and webpack.BannerPlugin, including the reported @license and @preserve comment variants. Compare the generated bundle with each plugin enabled; the issue is done when obfuscation and the banner both work together without losing the intended license comment.
