I have an element and depending on some condition, may set it's background. If the condition is first true, and later false the element is left with some "residual" styles that were never set in code.

Output looks like:

<!-- condition true -->
<div style="background: #ff0000"></div>

<!-- then when condition is false -->
<div style="background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial;"></div>

These styles were never set by user code, and are interfering with styles in my CSS.

Here's a fiddle showing the issue: http://jsfiddle.net/tfKYJ/78/
