specialComments and @media queries

I’ve been testing clean-css 4 in a project that I use it in.

I’ve noticed when using specialComments 0 inside code like this:

@media screen { 
/*!
    A special CSS comment
*/
}

The whole media query block is removed. Previously under clean-css 3, Having the same special comment within a media query block without any actual CSS rules (essentially an empty media query) would prevent this from happening, and the following would be left over.

@media screen {
}

I’m aware of some of the configuration changes between the versions, is there a specific option that’s causing this, that I can control?

@jakubpawlowicz Thanks! I actually use gulp-clean-css which acts as a wrapper, but I can manually test it by overriding the clean-css dep to a specific commit/branch.

It’s been released in 4.1 as described above.
