Multiline Headers (vertical border problem)

I am glad that there is a way to show multiple lines in a column header. Unfortunately the header vertical border is now not as long as the row is heigh which makes it no so appealing from a design point of view.

Yes, sorry - that was trivial bug in grid.css. Can be corrected with

.active-box-resize {
background-repeat: repeat-y;
}

How can it be done for the cells?
