 This div is absolutely positioned to the left. All the spaces in this div are replaced with non-breaking spaces, and the nbsp-mode for this div is 'space', so when calculating line breaks, the non-breaking spaces should be treated as normal spaces. If this isn't the case, then all the text for this paragraph will be rendered in two lines, and a horizontal scroll bar will appear along the bottom.
