.btn:active removes background image

Created by: TheDutchCoder

The active state of the .btn class removes a background image. What's the rationale behind this?

Some people (myself included) use a spritesheet to display background images and/or replace text elements (e.g. a Search button with a magnifying glass icon, instead of "Search").

I have one declaration for my spritesheets (.icon, .sprite {}) and like to keep it that way in order to prevent code bloating.

Would it be possible to leave the background image alone on the active state?
