chord symbols linked to a "fretdiagram"

I just noticed that in musescore 4.4 (i don't know about previous versions) chord symbols linked to a "fretdiagram" are included in the 'blue rectangle' selection. This means, unlike Musescore 3, they are available in curScore.selection.elements.
However:
1) they are not available in the cursor.next loop as 'annotations';
2) the child->parent hierarchy is unchanged;
3) as before, they are not transposable like those without "fretdiagram".
In any case, a step forward...
Also, the 'spannerTick(s)' property appears to have been removed, if anyone cares...
