It has been quite a while since the first submission of the issue. I have
written afterwards that the problem still exists! Anyone interested in this issue?
I think the problem is that the issue type is set to enhancement, when it was
actually a *defect*! The feature is already there: When you hover your mouse
over the footnote reference, footnote text appears but the display of the
footnote is defective! Maybe then will someone notice this problem!
ps. Since my first submission, I have changed location. As a result, the links
are not there anymore. When I have a chance, will submit new images.
