[Bug Report] Error when using media query with a hash getter

[l1qu1d]

I have break points that are predefined in a hash object that I use with @media queries. I use the VsCode extension and it won't format my stylus code when using the below code.

When I use a hash getter on the media query I get, "ERROR: Found an input node of null".

Steps to reproduce

Example code:
@media $display-breakpoints.md-and-up { }

Example hash:
$display-breakpoints := { md-and-up: "only screen and (min-width: %s)" % $grid-breakpoints.md }

To recreate the error just go to https://thisismanta.github.io/stylus-supremacy/ and go to the section "Try it in your browser". Paste the media query example code above.

Could you give me the full example code which works in http://stylus-lang.com/try.html please?

Could you verify my fix by installing the side-load extension?

Instructions can be found at https://code.visualstudio.com/docs/editor/extension-gallery#_install-from-a-vsix

Once the side-load extension has been installed, try repeating the issue above.

It works if the code is in its own .styl file now, but doesn't work if you're using it in a single file app like Vuejs.

Example: <style lang="stylus" scoped> @media $display-breakpoints.md-and-up { } </style>

I'm using your plugin along with Vetur plugin for VsCode.

Vetur extension must be updated separately.

For Stylus Supremacy, please upgrade to version 2.7.2 now.
For Vetur, please wait for PR vuejs/vetur#659 to be merged.
