Slide out tab SCSS: Restored "raw" content when printing.

Partially addresses gh-2733.

**PS:** On a side note, the diff makes this pull's changes look much more significant than they really are. I added screen media types around what's already present (along with tabbing for indentation) and revised the print media type's classes/properties. That's it. None of what's now situated within the screen media type was modified whatsoever.
