Description

Syntax highlighting seems to not work as expected. The @include rules show grey mixin names, instead of the usual blue color.

Steps to Reproduce

1. Open Atom
2. Make SCSS file with @include rule
3. Notice that the names of the included mixin is greyed out.

Expected behavior:

The mixin names should be highlighted in blue, as it was before today.
I think the @ before 'include' usually is also purple, not white.

Actual behavior:

It doesn't seem to recognize the @include rules.
Mixin names are grey colored.

Reproduces how often:

100%

Versions
