Very nice! While adapting the code to 2.25 and playing around I
noticed the following comment in the contained example:
```
%% Uncomment dynamic: box is sized to accommodate, but dynamic
%% is pushed aside.
g8%\p
```
What exactly is meant with 'accommodate'? Should there some vertical
space be reserved for the 'p' sign within the frame? If so, it seems
not to work: an activated `\p` is positioned outside of the frame, and
no space is reserved.
A bit later in the example there is a commented-out fermata; after
making the fermata active there is indeed such a vertical space
reserved, and prefixing `\fermata` with `\tweak outside-staff-priority
##f` makes the fermata actually become part of the frame.
