(Also, just FWIW, not that the code matters given the above, but: You're caching a global setting and not handling the case that it can be changed at runtime, so the patch would have needed work anyway, even if its underlying assumption had been correct -- which as mentioned it isn't, the 3 is just a coincidence.)

I found that the scroll event was being called as many times as set in the setting "wheelScrollLines" ("Mouse wheel scrolls by [X] lines" in system settings). It makes sense when scrolling on documents, but not here, so I'm scaling the steps by that value so it always change in steps the same (smaller) size.
