In Firefox and Internet Explorer, the "Remove Alignment" button does not correctly format text with text-align set using an inline style.

For example, if this is the HTML in the editor:

<p style="text-align: center;">Here is text that is center aligned</p>

In the Design editor, the "Remove Alignment" button looks selected, and pushing it has no effect (see screenshot).

In the Javascript, the remove alignment functions for Firefox and IE only remove styles from the DOM element, inline styles are not being removed.
