Okay, good point.
So what you do is actually to "emulate" tex to determine the correct
It is really a problem for me that math-mode do not get the correct
The bad solution is to left-justify the text (so that the length do not
affect the position) - and then use tex to centre:

\property Lyrics.LyricText \override #'X-extent-callback = #(lambda (gr
ax) '(-2.5 . 2.5))


This fixes the width of the words to 5 stafflines, but it works.
