MuseScore 4.4.1

Regression

I was unable to check

Operating system

Windows 11

Additional context

It should be possible with two or more grace notes to have a slur

Also MS4 crashes when you try to move the entire slur, I am not sure if this works in macOS as I currently don't have access to it.
