Library module scrolls uncontrollably

15.4 - Mac version - Apple Silicon

If I hold down the left or right arrows keys while in Library Module and I hold a touch too long (only like 1 second) it will scroll uncontrollably in that direction and it’s hard to get it to stop. (my shoots are large and it can easily scroll many hundreds of photos before I can get it to stop) 

This is a new behavior and did not do this in recent versions. (I believe there was a time years ago that this happened.) 

It does not happen in Develop Mode.
