I don't have this info (not have tried with that).  I see that the
footnote code meddles with spanner extents by querying
currentMusicalColumn which for automatic beams would seem like a pretty
bad idea (the musical column for ending the automatic beam being quite
to the right).  However, it appeared to me like disabling this code
(left and right) would not actually change anything, so either I did
something wrong when testing, or the code is not actually triggered or
not involved.
