* 1.3 em away so that the entire text-decoration covers
* the vertical box. Its text-decoration should grow "out"
* away from the text, covering up the scrollport. We
* will use 1.5 em-wide decoration line to be sure the
* scrollport is still fully covered if there are small
* differences in the placement of the line.
