HI there. A quick bug to report:
On diads with a split stem, articulations are placed above both note-heads, like you’d expect.
However, the articulations are not properly aligned, nor can you adjust their positions independently to fix the issue.
See the attached picture for an example.
When you say “properly aligned”, do you mean that they are not both at precisely the same vertical position relative to the notehead, or something else? (Just so I’m sure I understand the problem you’re reporting.)
Right. That is what I mean.
I can’t see why they should be at different vertical positions.
You’re probably right that they shouldn’t be at different vertical positions, but the one on the main stem is moved by a fixed amount to avoid the tie, I think, whereas the one on the split stem is tucking in closer to the curvature of the tie.
In the image I originally attached, I had manually moved the accents up to avoid a collision with the tie. I’m attaching to this post another image with an unaltered example of the problem, where the lower of the two accents collides with the tie.
