Bluetooth (Magic) Mouse scrolling inertia broken in Sequoya?

MacBook M1 Pro, Sequoya 15.5

Using inertia in scrolling lets the page continue to float and stop smoothly after the swipe up or down. This works OK from the trackpad (two-finger swipe), but stopped working with my Bluetooth (Magic) Mouse. Now the mouse scroll stops dead after the swipe. The default mouse inertia option is On. I've tried turning it off and back on. I've reinstalled the Sequopya 15.5 update. Did the system update break it? Did someone decide I should use the trackpad only?

MacBook Pro 14″

I would try a different magic mouse and compare the results.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.
