I think I'm seeing the same thing on my Mac that you're describing, modelmac. There's a whole other scrolling possible with trackpads, and that's being able to scroll all 52 or 100 weeks in one long scroll, or 12 months in one long scroll. You can even stop and see half of one month on the top and half of the next on the bottom.
I just heard back from the creator of a mouse utility called
SteerMouse, which I've used for 10 years or so. He says it's a "known issue." -

"It is a known issue. Only gesture devices are available for scrolling of the month view.
It is the behavior of Calendar.app. SteerMouse is not able to solve it."
