BIAB does, and has ever since note lyrics was introduced, had a real problem printing "long" lyrical phrases.

It does not seem to recognize when there are too many lyric elements to fit in a bar so overflow or stacking often occurs.

My work around is to either reduce the number of bars on a line or make one large element out of two or more smaller elements. So 3 syllables such as 'in' 'the' 'night' becomes one syllable, 'in the night' attached to the first note. Some times it works, other times not.

The introduction of bar based lyrics helped some of those who were still on line based lyrics but needed more control, but it has caused some problems since it seems to want to centre everything.

You can change the lyric size, bars per line and even lines per page, but it is really only a work around and the problem is still there.
