Support for font-display

[acupofspirt]

I am use CSSTree as a plugin for Gulp. And when I trying to use font-display property it fails with 'unknown property' error. Can you add support for that property?

Yes please, font-display is quite common these days and this golden dot makes me want to disable this plugin again :(

It will be supported when CSSTree gets ability to check at-rule descriptors (soon). Some other descriptors works fine by incident – they have similar syntax as declarations with the same name, but these are all different things.

That's not an issue anymore. Since CSSTree validate at-rules in a different way starting from 1.1.0, using at-rule definitions.
Latest version of VS Code plugin should work fine.
