Emmet Stylus snippets not working

[ngoov]

The Stylus snippets that come out of the box with Emmet do not work in VSCode, while the default setting in the 'preferences.json' (that is nowhere to be found) of Emmet 'css.syntaxes -
List of syntaxes that should be treated as CSS dialects.' has .styl

• VSCode Version: 1.0.0
• OS Version: Windows 8.1 Enterprise

Steps to Reproduce:

1. Create a .styl file
2. Add a CSS selector: ex. #test
3. Type pos:a and press TAB

Expected result: expands to 'position absolute' or 'position: absolute;'
Actual result: nothing happens
