Whole note stem direction affects horizontal position of lyrics

Steps to reproduce
1. Create a score with at least two staves.
2. Add a whole note to each staff in the first measure such that their stems would be in opposite directions.
3. Add a lyric to each whole note.

Expected: The lyrics are aligned.
Observed: The lyrics are misaligned.

You can press X on a whole to observe the effect. This issue comes up when transcribing a song with multiple singers, such as one for an SATB choir. If everyone's on a whole note, the "stem direction" of the notes causes the corresponding lyric to be offset, and then the lyrics are no longer perfectly aligned. A temporary solution is to force all whole note stems to one direction.
