UP/DOWN shortcuts don't work with musescore 4

[ALLY1950]

Describe the bug
UP/DOWN shortcuts don't work with musescore 4

To Reproduce

1. Download musescore 4 AppImage and xen-tuner plugin.zip
2. Extract the content of zip into /Documents/Musescore4
3. Disable all default shortcuts for pitch UP/DOWN and select notes up/down, as screenshots indicate
   
   
4. Enable plugin in Musescore 4 and make sure it's runing, as screenshots indicate, ALT+R tuning is working, proved by displaying cents and steps
   
   
5. Displaying cents doesn't work for 41 edo but works for 311 edo
   

TUNING CONFIG: first tried hewm/311edo. I thought the edo might be too large for up and down work properly, I also tried hemw/41 edo, but UP/DOWN still doesn't work


**Environment:**
OS: Linux Mint 21.2, Arch.: x86_64, MuseScore version (64-bit): 4.1.1-232071203, revision: github-musescore-musescore-e4d1ddf

Any news on fixing this @euwbah ? I tried this with Musescore 3 but arrow keys do absolutely nothing on both musescore 3 and 4. If I manually add microtonal accidentals from Musescore's built-in pool of accidental signs, and then hit Alt R, the tuning will become unexpectedly weird, all notes with different accidentals now are playbacked to be the same pitch. The entire experience just feels like this plugin is significantly broken. If I understand correctly, I should be able to circle through different microtone accidentals by simply hitting up and down arrow keys, but this is completely unusable as it's broken like this. Any hope on fixing this?

Same with me. I cannot use the arrow keys in MS4. it works for me in MS3, though.
