"not" notation when using @support API

[SelfishLucho]

Hi! I tried to find documentation or some sort of report issue but was not able to, If someone could pin point on where I should look to find my issue. I know that i can work around this but still would like to know how cssnano categories this.

Im trying to use the "not" notation when using @support API, however doesn't seem to trigger properly when using cssnano. Is there an option possibly I'm missing here that I should use or something needed to take in consideration when running nano?

Here is a codepen on the css I'm trying to run

@SelfishLucho can you provide examples?

[SelfishLucho]

@evilebottnawi the codepen :), or do you want me to update it here?

[alexander-akait]

@SelfishLucho what is broken? @support cannot be nested

[SelfishLucho]

@evilebottnawi When using @support not (style), "not" notation is not being taken in consideration by cssnano

[SelfishLucho]

@evilebottnawi Ok I try to use it without nesting it

@SelfishLucho can't reproducible 😕 here link on playground https://cssnano.co/playground/

@evilebottnawi Seems like it's actually including the "not" notation, but I will try without nesting that might be causing my issue. Is there a way find what compiling options the playground is using?

[alexander-akait]

@SelfishLucho no options, safe mode

Tests added for not notation #708 and all work as expected.
