A top left margin box width is not correct when content is taken from a css variable
On pages 2 and 3, there is some content in @top-left and @top-right
As you can see on page 2, the @top-left width is correct, and text is properly wrapped. On page 3, the @top-left width is incorrect. The only difference is that for page 3 the @top-left content is taken from a string-set variable, and for page 2 the @top-left content is a plain string.
