How to inspect and edit ornaments inline in the notation editor

When you are in the Notation editor and have an ornament selected, Notation → Notes → Ornaments → Show Expansion of Ornament will show a (fake) segment of how the ornament is performed, including any transposition and any clipping of start and end.

Notation → Notes → Ornaments → Edit Ornament as Notation does something similar, except you can edit it, which will permanently change the ornament.
