Start/end ignore comments not detected when they don't precede a rule

First of all, thank you so much for developing my feature request (#66). It works great in most cases, but I just found an issue with it. It seems the /*! purgecss start ignore */ comment is ignored if it’s the first line in the CSS file, so the block isn’t ignored. I’m using Laravel Mix with the laravel-mix-purgecss plugin. Let me know if you need any more information. Thank you!

add ! after /*

These works on webpack 4

/*! purgecss start ignore */
/*! purgecss end ignore */

I read on cssnano docs on how to preserve the comments https://cssnano.co/optimisations/discardcomments/

@Remeic Just ran into this. My issue was that cssnano was running before PurgeCSS and stripping out comments.
