Please, check this video.
This is me trying to slide this region to bar 45 (1 1 1).
After a I release the mouse, it landed in bar 44 (4 1 1).
Important to note, I'm dropping the region using the very same mouse maneuver I used to do every single day since 2014 on a number of different systems and it always landed in the right place.
Now that I just got the new M3 max with Sonoma and Logic 10.8.1, I would say this bug happens around 45% of the time, and please note the region can land in different wrong spots.
