footnotes to lyrics

[Mogens Lemvig Hansen]

How do I get a footnote to lyrics – is it even possible.  In the example below, “Sing” doesn’t get a footnote mark, “this doesn’t” vanishes, and no error message is given.

 

\version "2.23.11"

 

\markup { Some \auto-footnote regular "this works" text. }

 

\score {

  { c d e f g }

  \addlyrics { \markup { \auto-footnote Sing "this doesn't" } an -- oth -- er song. }

}

 

Thanks,

Mogens
