The diminuendo (text/hairpin) does not work if a dynamic mark doesn't exist at the end

Issue type

General playback bug

Description with steps to reproduce

Steps to reproduce

1. Create/open the score with a wind/string instrument
2. Enter any note within the available range
3. Add the aa dynamics to the note you just entered.
4. Add a diminuendo stud after the introduced dynamics
5. Click Play.

Expected behaviour

It was expected that the loudness would decrease, but this did not happen. (Even if the volume has changed, it is only by some microns, which is clearly not enough, especially at a slow tempo.)

Additional context

It has nothing to do with whether the notes are tied or not. The bug works regardless of this.

I didn't just put "in a number of cases" in the title of the issue. In some cases, the diminuendo works fine (for example, if it is notated immediately after the crescendo). To be honest, I didn't have enough time to analyze in detail all the situations in which this bug can work. It is possible that along with the diminuendo, the same thing may happen with the crescendo.
