HI Marc and Rouslan,
I tried on your demo server and as far as I can tell the tooltips are
completely broken now. They are no longer generated for the normal page
(but the footnotes are hidden) and they don't appear in the ajax dialog
(the footnotes, again, are gone though) (ubuntu 11.04/firefox 5).
Also as Marc said, with the code that you committed you would be
generating duplicate IDs, I suggest you merely change those to classes
to avoid possible conflicts (or you could come up with some scheme for
generating unique IDs, though that sounds more complicated than is
necessary).
