Tremolos and Fermatas for small chords remain big in 3.x, were small in 2.x
In Version 2.3.2 when I put a one-note-tremolo on a small chorded note (when I tick the box "small chord"-box (there stands "Akkord" (german for chord) and then there is the box with "klein" (small) to tick at the inspector)) or also when I first put the tremolo on the note and then select it and tick the box "small chord" the tremolo sign stays in the normal size. In erlier versions the tremolo sign went small to, what I prefer for cue notes.
I'll attache two files to compare it. Have a look at rehearsal H and a few bars before rehearsal P.
The Kl1-file was made with an earlier version (I think its 3.1, and having small tremolos on the cue notes), The Kl2 file is made with Version 3.2.3.
PS: In Version 2 tremolos on small chords also went small.
