Voice misalignment under special circumstances
Here's the scenario:
With a grand-staff (harp for instance, especially since this style of notation occurs often with that instrument)
Have three voices two on lower staff with one cross-staffing upward, and one on first voice on the treble. The treble clef will have half notes, the cross-staff 8th notes, and the bottom voice will be a whole tone.
What happens is that the cross staffed notes will be misaligned with the half notes above it. This only happens when there's a whole note involved down below
2.) If there were half notes instead down below, it works just fine, i.e.:
3.) Here the problem becomes more pronounced in the misalignment if the desire is to have these share the same voice and show only one note head (the stems are terribly aligned for this purpose upon the default outcome):
4.) otherwise, they work fine with e.g. half notes below:
The work around so far is to move the first 8th note over with a chord-offset about +0.3spacing, but offsetting the whole note in anyway does nothing to fix the issue, but it seems that this should all be automatic and not require such a customization...
How would this be fixed or described for someone to fix it not as a customized workaround but as a code fix? It might be easy, but it might be complicated related to the layout algorithms...
P.S., If the 8th notes here were in the second voice of the upper staff, the algorithm works just fine! So based upon how MS currently is, apparently it does matter from which staff one crosses over. Maybe there's a reason for this that's not being understood? Here's a gif showing a quick Exchange Voices 1-2 at the bottom to demonstrate that it fixes it. It's almost humorous to watch the misalignment occur and leave again:
