Content component background color is not respected

[michaelbeil]

When a user creates a content component with an image as the background, leaving the background color blank, the default background-color:#222222 is seen from the front-end. The expected result is for the text to be placed on top of the background image without a block of color surrounding the inserted text. This happens in select themes, like AST, Custom Community, and the theme here: http://sendasos.com/index.php/2015/05/10/about.

Theme styles seem to be overriding that div.
