Using Articulation Shortcuts (Or any shortcut using Shift) Change Note Input Behaviour

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

1. Click on a note
2. Enter note input mode (N)
3. Use a shortcut to select an articulation (Shift+V, Shift+O, for example)
4. Enter a note with midi keyboard

Expected behaviour: Existing note is overwritten with the selected articulation applied
Actual behaviour: A new note is added to the previous one with the new articulation

Playing around with things a bit more, it would seem that pressing Shift once and then releasing is enough to make the next note be added to the existing note to form a chord (oddly enough, holding Shift and entering a note does not do this, as I would have expected). Pressing Shift+whatever will select the articulation, but also the (presumably buggy) behaviour of pressing and releasing shift also falls through.

Based on this, it looks like this is related to #26447 . You can add a note to an existing one, just you need to tap shift once, rather than pressing and holding, which does not work.
